Description

本発明は非水系二次電池の正極合剤含有組成物若しくは負極合剤含有組成物又は水系二次電池の正極合剤含有組成物若しくは負極合剤含有組成物といった二次電池の電極合剤含有組成物、特にスラリー化された電極合剤含有組成物の連続製造装置及び連続製造方法に関する。   The present invention includes a secondary battery electrode mixture containing a positive electrode mixture-containing composition or negative electrode mixture-containing composition of a non-aqueous secondary battery or a positive electrode mixture-containing composition or negative electrode mixture-containing composition of an aqueous secondary battery. The present invention relates to a continuous production apparatus and a continuous production method of a composition, in particular, a slurryed electrode mixture-containing composition.

電池材料の調合方法として従来からバッチ式の混練方法が用いられてきた。
一方、電池の種類の観点からすると、リチウム二次電池に代表される二次電池が既に広く利用されるようになっており、その用途は携帯電話、パーソナルコンピューター、電動工具等の比較的小型の機器にとどまらず、今日では自動車用へ著しい広がりをみせている。
Conventionally, a batch-type kneading method has been used as a method for preparing battery materials.
On the other hand, from the viewpoint of the type of battery, a secondary battery represented by a lithium secondary battery has already been widely used, and its application is relatively small such as a mobile phone, a personal computer, and an electric tool. Today, it is not limited to equipment, but is now spreading significantly to automobiles.

この時流にともない、二次電池の生産量は今後従来の数十倍或いは数百倍以上に飛躍的に増大すると見込まれる。
このような状況の中では、従来のバッチ式生産方式では生産量増加の要請に対応できない。また、バッチ式生産方式は人件費等から派生するランニングコストの押上げにもつながり、同方式による電池生産システムはこの点からも将来性に問題がある。
Along with this trend, the production amount of secondary batteries is expected to increase dramatically in the future to several tens or several hundred times the conventional amount.
Under such circumstances, the conventional batch production method cannot meet the demand for an increase in production. In addition, the batch production method leads to an increase in running cost derived from labor costs, and the battery production system using this method also has a problem in the future.

そのため、電池生産の多量生産化時代に向けてバッチ式から連続式への移行を強く迫られている。
この点、例えば特開2007−220510号公報に記載されている電池材料の連続剪断処理装置によると、電池材料の混合とメカノケミカル処理を同時的、連続的に行うことができ、この連続剪断処理装置及び該装置による電池の正極合剤含有組成物や負極合剤含有組成物の製法は電池量産増大の要請に少なからず応えられると考えられる。
For this reason, there is an urgent need to shift from batch type to continuous type for the era of mass production of battery production.
In this regard, for example, according to the battery material continuous shearing apparatus described in Japanese Patent Application Laid-Open No. 2007-220510, the battery material mixing and the mechanochemical treatment can be performed simultaneously and continuously. It is considered that the device and the method for producing a positive electrode mixture-containing composition and a negative electrode mixture-containing composition for a battery by the device can respond to the demand for an increase in battery mass production.

特開2007−220510号公報JP 2007-220510 A

しかし、今日の二次電池は、正極合剤含有組成物としてスラリー化された正極合剤含有組成物を用い、これを集電体に塗布して正極合剤層を有する正極を形成するとともに、負極合剤含有組成物としてスラリー化された負極合剤含有組成物を用い、これを集電体に塗布して負極合剤層を有する負極を形成し、これら正極及び負極をセパーレータを介して積層した電極体と、非水系電解液又は水系電解液とを電池外装ケース内に装填して形成するのが一般的である。   However, today's secondary batteries use a positive electrode mixture-containing composition that is slurried as a positive electrode mixture-containing composition, and this is applied to a current collector to form a positive electrode having a positive electrode mixture layer. Using the slurry-containing negative electrode mixture-containing composition as the negative electrode mixture-containing composition, this is applied to a current collector to form a negative electrode having a negative electrode mixture layer, and the positive electrode and the negative electrode are laminated via a separator. In general, the electrode body and a non-aqueous electrolyte solution or an aqueous electrolyte solution are loaded in a battery outer case.

従来のバッチ生産方式によると、ビーズミルのような分散機を用い事前に正極活物質や負極活物質と導電助剤を混合分散処理しておき、これをプラネタリーミキサーのような機械を用いてスラリー化する方法がとられる。この方法によると、正極合剤含有組成物スラリーや負極合剤含有組成物スラリーを正極活物質や負極活物質等を出発原料として一貫して連続的に生産することはできない。   According to a conventional batch production system, a positive electrode active material, a negative electrode active material, and a conductive auxiliary are mixed and dispersed in advance using a disperser such as a bead mill, and this is slurried using a machine such as a planetary mixer. The method of becoming is taken. According to this method, the positive electrode mixture-containing composition slurry and the negative electrode mixture-containing composition slurry cannot be continuously produced continuously using the positive electrode active material, the negative electrode active material, and the like as starting materials.

特開2007−220510号公報記載の連続剪断処理装置によっても、正極合剤含有組成物スラリーや負極合剤含有組成物スラリーを一貫して連続的に生産することはできない。   Even with the continuous shearing apparatus described in JP-A-2007-220510, the positive electrode mixture-containing composition slurry and the negative electrode mixture-containing composition slurry cannot be produced consistently and continuously.

同公報の記載によると、例えば、正極合剤含有組成物スラリーの調製にあたっては、正極活物質を連続剪断装置を用いて処理し、その後に、別途準備されたプラネタリーミキサー等の混合装置を用いて、該正極活物質と、導電助剤、結着剤及び溶剤とを従来どおりの混合方法で混合して正極合剤含有組成物スラリーが調製される。   According to the description of the publication, for example, in preparing the positive electrode mixture-containing composition slurry, the positive electrode active material is processed using a continuous shearing device, and then a separately prepared mixing device such as a planetary mixer is used. Then, the positive electrode active material, the conductive additive, the binder, and the solvent are mixed by a conventional mixing method to prepare a positive electrode mixture-containing composition slurry.

或いは、正極活物質及び導電助剤を前記連続剪断装置を用いて処理し、そうして得られる混合物を別途準備されたプラネタリーミキサー等の混合装置を用いて結着剤及び溶剤と従来どおりの混合方法で混合してスラリー化された正極合剤含有組成物が調製される。   Alternatively, the positive electrode active material and the conductive additive are treated using the continuous shearing device, and the mixture thus obtained is mixed with the binder and the solvent using a mixing device such as a planetary mixer separately prepared. A positive electrode mixture-containing composition that is mixed and slurried by a mixing method is prepared.

スラリー化された負極合剤含有組成物の調製も略同様である。   The preparation of the slurry-containing negative electrode mixture-containing composition is substantially the same.

同公報には、正極活物質又は負極活物質、導電助剤、結着剤及び溶剤を一度に前記連続剪断装置に投入して処理することができる旨の記載があるが、このように多種類の電池材料を一度に連続剪断処理装置へ投入して所望の混合とメカノケミカル処理をそれら材料に一挙に施して、それら材料が均一に混合分散されたスラリー化された組成物を得ることは実際には困難であると思われる。   In this publication, there is a description that a positive electrode active material or a negative electrode active material, a conductive auxiliary agent, a binder and a solvent can be put into the continuous shearing device at once and processed. It is actually possible to obtain a slurry composition in which the battery materials are uniformly mixed and dispersed by putting the battery materials into a continuous shearing device at once and applying the desired mixing and mechanochemical treatment to the materials all at once. Seems to be difficult.

そこで本発明は、二次電池形成のための電極合剤含有組成物スラリー塗布対象材への塗布工程に供することができる均質な電極合剤含有組成物スラリーを少なくとも粉体の電極活物質を含む粉体電池材料を出発原料として目的とする電極合剤含有組成物スラリーまで一貫して連続的に再現性良好に製造することができる二次電池用の電極合剤含有組成物スラリーの連続製造装置及び連続製造方法を提供することを課題とする。   Therefore, the present invention includes at least a powdered electrode active material in a homogeneous electrode mixture-containing composition slurry that can be subjected to an electrode mixture-containing composition slurry application target material for forming a secondary battery. Continuous production apparatus for electrode mixture-containing composition slurry for secondary battery capable of producing continuously and reproducibly good electrode mixture-containing composition slurry using powder battery material as starting material It is another object of the present invention to provide a continuous manufacturing method.

ここで、「電極合剤含有組成物」は、「正極合剤含有組成物」であっても、「負極合剤含有組成物」のいずれであってもよく、またそれらは、「非水系二次電池」用のものでも、「水系二次電池」用のものでも構わない。   Here, the “electrode mixture-containing composition” may be either a “positive electrode mixture-containing composition” or a “negative electrode mixture-containing composition”. Secondary battery "or" aqueous secondary battery "may be used.

また、粉体電池材料を構成する「電極活物質」は「正極活物質」でも「負極活物質」でも構わない。粉体電池材料を構成するものとして電極活物質の他に粉体の添加剤が採用されてもよく、その場合、粉体の添加剤として粉体の導電助剤を例示できる。   The “electrode active material” constituting the powder battery material may be a “positive electrode active material” or a “negative electrode active material”. In addition to the electrode active material, a powder additive may be employed as a constituent of the powder battery material. In this case, a powder conductive additive may be exemplified as the powder additive.

正極合剤含有組成物スラリーを製造する場合には、粉体電池材料として粉体の正極活物質と粉体の導電助剤を含むものを例示できる。
負極合剤含有組成物スラリーを製造する場合には、粉体電池材料として粉体の負極活物質、或いは粉体の負極活物質と粉体の導電助剤を含むものを例示できる。
In the case of producing a positive electrode mixture-containing composition slurry, examples of the powder battery material include a powdered positive electrode active material and a powder conductive aid.
When the negative electrode mixture-containing composition slurry is produced, examples of the powder battery material include a powder negative electrode active material, or a powder containing a powder negative electrode active material and a powder conductive assistant.

本発明の二次電池用の電極合剤含有組成物スラリーの連続製造装置及び該装置を用いる二次電池用の電極合剤含有組成物スラリーの連続製造方法によると、少なくとも粉体の電極活物質を含む粉体電池材料を出発原料として、該粉体電池材料を構成する各材料を計量して、それら材料を予め定めた配合割合で前記供給部からメカノケミカル処理部へ供給することができ、しかも連続的に供給することが可能である。   According to the continuous production apparatus for the electrode mixture-containing composition slurry for the secondary battery of the present invention and the continuous production method for the electrode mixture-containing composition slurry for the secondary battery using the apparatus, at least the powdered electrode active material The powder battery material containing the starting material, the materials constituting the powder battery material are weighed, and these materials can be supplied from the supply unit to the mechanochemical processing unit at a predetermined blending ratio, Moreover, it is possible to supply continuously.

そのようにメカノケミカル処理部に供給された粉体電池材料は、メカノケミカル処理部における剪断分散処理域を通過することで剪断力と分散作用を受けて均一状に混合されるとともに相互に分散された状態の、且つ、その分散状態がその後の各種処理においても維持される、換言すれば、その後の処理おいても電池材料を構成している一部の材料等が再凝集することが抑制された状態が維持されるメカノケミカル処理物となる。   The powder battery materials supplied to the mechanochemical processing section are mixed uniformly and subjected to shearing force and dispersion action by passing through the shear dispersion processing area in the mechanochemical processing section. In this state, the dispersed state is maintained in various subsequent processes. In other words, the re-aggregation of some materials constituting the battery material is suppressed even in the subsequent processes. This is a mechanochemically treated product that maintains its state.

このメカノケミカル処理物はひき続き硬練混練分散処理部へ送られ、該処理部で予め定めた配合割合となるように供給される液状のバインダーとともに混練分散処理される。該混練分散処理においても液状バインダーとメカノケミカル処理物とが該処理部における前記剪断分散処理域を通過することでそれらは均一状に混練されるとともに相互に均一状に分散される。 The mechanochemically processed product is subsequently sent to a kneading and kneading dispersion processing section, where it is kneaded and dispersed together with a liquid binder supplied so as to have a predetermined blending ratio. Also in the kneading and dispersing treatment, the liquid binder and the mechanochemically treated product pass through the shear dispersion treatment area in the treatment section, so that they are uniformly kneaded and dispersed uniformly.

この場合、液状バインダーは水飴状の粘度のバインダーであることが一般的であり、そのような場合には、そのまま塗布工程に供するには未だ適さない比較的硬練りの混練物(硬練混練物)が得られる。 In this case, the liquid binder is generally a water- binder- like viscosity binder. In such a case, a relatively kneaded kneaded material (kneaded kneaded material that is not yet suitable for use in the coating process as it is. ) Is obtained.

この硬練混練物はひき続き希釈混練分散処理部へ送られ、該処理部で予め定めた配合割合となるように供給される液状の希釈剤とともに混練される。該混練処理においても液状希釈剤と硬練混練物とが該処理部における前記剪断分散処理域を通過することでそれらは均一状に混練されるとともに相互に均一状に分散され、かくして、均質な、塗布工程に供することができる適度の粘度の二次電池用の電極合剤含有組成物スラリーが品質再現性良好に連続的に得られる。   This kneaded and kneaded material is subsequently sent to a dilution kneading and dispersing treatment section, where it is kneaded together with a liquid diluent supplied so as to have a predetermined blending ratio. Also in the kneading treatment, the liquid diluent and the kneaded kneaded material pass through the shear dispersion treatment area in the treatment section, so that they are uniformly kneaded and are uniformly dispersed with each other. An electrode mixture-containing composition slurry for a secondary battery having an appropriate viscosity that can be used in the coating step is continuously obtained with good quality reproducibility.

本発明に係る二次電池用の電極合剤含有組成物スラリーの連続製造装置及び連続製造方法によると、少なくとも粉体の電極活物質を含む粉体電池材料を出発原料として目的とする電極合剤含有組成物スラリーまで一貫して連続的に再現性良好に同じ製造装置で製造することができるから、出発原料である粉体電池材料から最終的に電極合剤含有組成物スラリーを得るまでの間にそれぞれ機能の異なる複数台の装置を必要とすることがなく、それだけ装置コストの面からも、人件費の面からもコスト安に済み、ランニングコストも安価に済み、しかも効率よく所望量の電極合剤含有組成物スラリーを得ることができる。   According to the continuous production apparatus and the continuous production method of the electrode mixture-containing composition slurry for the secondary battery according to the present invention, the electrode mixture intended for the starting material is a powder battery material containing at least a powder electrode active material. From the powder battery material that is the starting material until the electrode mixture-containing composition slurry is finally obtained, it can be manufactured continuously and continuously with good reproducibility up to the contained composition slurry. This eliminates the need for multiple devices with different functions, reduces the cost of both the device and labor, reduces the running cost, and efficiently produces the desired amount of electrodes. A mixture-containing composition slurry can be obtained.

また、粉体原料を混合処理したのちに、その処理物を別途用意したプラネタリーミキサー等に移し替えてバインダー等と混練するバッチ処理を行う場合と比べると、粉塵飛散による作業環境の汚染、悪化が抑制され、電極合剤含有組成物への異物の混入が生じ難く、さらにロット毎の品質のバラツキの問題も生じ難く、それだけ高品質で、品質の安定した電極合剤含有組成物スラリーを効率良く連続的に得ることができる。   Compared with batch processing in which powder raw materials are mixed and then transferred to a planetary mixer, etc., prepared separately and kneaded with binder, etc., contamination and deterioration of the working environment due to dust scattering In this way, it is difficult for foreign matter to mix into the electrode mixture-containing composition, and it is difficult to cause quality variations from lot to lot. It can be obtained well and continuously.

各材料が所定割合で配合された粉体電池材料は別途計量準備しておいて、例えば前記供給部にホッパ等をから連続的に投入するようにしてもよいが、前記供給部に前記粉体電池材料を構成するそれぞれの材料に対応させて、材料配合割合が予め定めた配合割合となるように該材料を計量して前記供給部へ投入するための計量器を接続しておいてもよい。
これにより、より効率的に粉体電池材料を供給部へ投入することができる。
The powder battery material in which each material is blended at a predetermined ratio is separately prepared for measurement, and for example, a hopper or the like may be continuously fed into the supply unit. In correspondence with each material constituting the battery material, a measuring device for measuring the material and feeding it to the supply unit may be connected so that the material mixing ratio becomes a predetermined mixing ratio. .
Thereby, powder battery material can be more efficiently thrown into a supply part.

前記供給部から前記メカノケミカル処理部へ供給される前記粉体電池材料が前記粉体電極活物質のほか少なくとも1種の粉体添加剤(例えば導電助剤)を含むものである場合、 前記メカノケミカル処理部としては、該供給部から供給される該電極活物質と該添加剤(例えば導電助剤)とを混合するとともに該電極活物質の周囲に少なくとも一種の前記添加剤(例えば導電助剤)を散点状に分散配置するスポットメカノケミカル処理を実施するメカノケミカル処理部である場合を例示できる。   When the powder battery material supplied from the supply unit to the mechanochemical processing unit includes at least one powder additive (for example, a conductive additive) in addition to the powder electrode active material, the mechanochemical processing As the part, the electrode active material supplied from the supply part and the additive (for example, conductive assistant) are mixed and at least one kind of additive (for example, conductive assistant) is mixed around the electrode active material. The case where it is a mechanochemical process part which implements the spot mechanochemical process dispersively arranged in the shape of a dot can be illustrated.

このようなスポット型メカノケミカル処理により、添加物(例えば導電助剤)はその後の処理においても凝集し難く、電極活物質から剥離し難く、電極活物質の周囲に散点状に分散配置された状態が良好に維持され、それだけ最終的に得られる電極合剤含有組成物スラリーの品質が高品質なものとなる。   By such a spot-type mechanochemical treatment, the additive (for example, the conductive auxiliary agent) hardly aggregates in the subsequent treatment, hardly peels off from the electrode active material, and is dispersedly arranged around the electrode active material. The state is maintained well, and the quality of the finally obtained electrode mixture-containing composition slurry becomes high.

また、このようなメカノケミカル処理によると、電池材料として電極活物質のほかに嵩高い導電助剤を採用する場合でも、導電助剤が均一に分散されることで、電池の充填密度を向上させることができ、その割りには、導電助剤の配合割合をそれだけ少なく済ませることができる。
さらに吸油量の多い導電助剤の配合割合を小さくできるので、それだけバインダー配合割合も少なく済ませることができ、これらにより、各処理を効率的に行うことができ、原料費を抑制することもできる。
Also, according to such a mechanochemical treatment, even when a bulky conductive aid is employed as the battery material in addition to the electrode active material, the conductive aid is uniformly dispersed, thereby improving the packing density of the battery. For that reason, the blending ratio of the conductive auxiliary agent can be reduced accordingly.
Furthermore, since the blending ratio of the conductive auxiliary agent having a large oil absorption amount can be reduced, the blending ratio of the binder can be reduced accordingly. With these, each treatment can be performed efficiently and the raw material cost can be suppressed.

前記環状固定円盤と前記回転円盤との隙間に入り込む処理対象材料に前記剪断分散処理を施す剪断分散処理域としては、該環状固定円盤の該回転円盤に向けられた面に形成された凹所(キャビティ)と、該回転円盤の該環状固定円盤に向けられた面に形成された凹所(キャビティ)とを含んでいるものを例示できる。
環状固定円盤の凹所(キャビティ)及び回転円盤の凹所(キャビティ)は、それら凹所に捕捉される処理対象材料が該固定円盤に対する該回転円盤の回転に伴って凹所内に旋回流が形成されつつ移動する際に剪断力を受けるとともに分散せしめられる凹所である。
As a shear dispersion treatment area for subjecting the material to be processed entering the gap between the annular fixed disk and the rotating disk to the shear dispersion treatment, a recess formed on the surface of the annular fixed disk facing the rotating disk ( Examples include a cavity) and a recess (cavity) formed in a surface of the rotating disk facing the annular fixed disk.
In the recesses (cavities) of the annular fixed disk and the recesses (cavities) of the rotating disk, a swirl flow is formed in the recesses as the processing target material captured in these recesses rotates with respect to the fixed disk. It is a recess that receives a shearing force and is dispersed when moving while being moved.

また、環状固定円盤の凹所(キャビティ)の縁と該回転円盤の凹所(キャビティ)の縁とは、回転円盤の回転に伴ってそれら縁がすれ違うときに、該回転円盤の上流側の面においては処理対象材料が該回転円盤の円周側へ送られ、該回転円盤の下流側の面においては処理対象材料が該回転円盤の回転軸側へ送られるように、円盤半径方向に対する延び方向角度(固定円盤の凹所縁及び回転円盤の凹所縁間の相対角度)が調整されている。
回転円盤の外周部には、前記供給部による電池材料送り方向と同方向に処理対象材料を送る送り部材(例えばスクリュー様の送り部材)が形成されていてもよい。
Further, when the edge of the recess (cavity) of the annular fixed disk and the edge of the recess (cavity) of the rotating disk pass with each other as the rotating disk rotates, the upstream surface of the rotating disk In the direction of extension with respect to the radial direction of the disk so that the material to be processed is sent to the circumferential side of the rotating disk and the material to be processed is sent to the rotating shaft side of the rotating disk on the downstream side of the rotating disk. The angle (relative angle between the recessed edge of the fixed disk and the recessed edge of the rotating disk) is adjusted.
A feed member (for example, a screw-like feed member) that feeds the material to be processed in the same direction as the battery material feed direction by the supply unit may be formed on the outer peripheral portion of the rotating disk.

処理対象材料を円滑に送るために、各隣り合う前記回転円盤の間に位置する前記回転軸の部分には処理対象材料を前記供給部による電池材料送り方向と同方向に送るための、例えばスクリューのような中間送り部材を設けてもよい。   In order to smoothly feed the material to be treated, for example, a screw for feeding the material to be treated in the same direction as the battery material feeding direction by the supply unit to the part of the rotating shaft located between the adjacent rotating disks An intermediate feed member such as

電極合剤含有組成物スラリーの汚染を抑制するために、前記電池材料と接触する部分の表面を耐摩耗性溶射材料膜で被覆してもよい。
耐摩耗性溶射材料膜としては、タングステンカーバイトの溶射膜を例示できるが、アルミナ、ジルコニア等のセラミック材料の溶射膜を採用することもできる。
In order to suppress contamination of the electrode mixture-containing composition slurry, the surface of the portion in contact with the battery material may be coated with a wear-resistant sprayed material film.
As the wear-resistant sprayed material film, a tungsten carbide sprayed film can be exemplified, but a ceramic material sprayed film such as alumina or zirconia can also be employed.

前記の希釈処理を行う希釈混練分散処理部は、その前段の処理部で得られた硬練混練物を段階的に円滑に薄められるように前記供給部による前記電池材料の送り方向と同方向に複数段に設けられていてもよい。 The dilution kneading dispersion processing section for performing the dilution processing is performed in the same direction as the feeding direction of the battery material by the supply section so that the kneaded kneaded material obtained in the previous processing section can be thinned smoothly in a stepwise manner. It may be provided in a plurality of stages.

例えば2段に設けることができ、その場合、例えば次のように設けることができる。
すなわち、前記供給部における電池材料送り方向と同方向において上流側段の希釈混練分散処理部は前記液状希釈剤として液状の一次希釈剤を投入するための一次希釈剤投入部を有し、該一次希釈剤投入部から投入される一次希釈剤と前記硬練混練分散処理部から供給される前記硬練混練物とを混練するとともに相互に分散させて一次希釈物を得るための一次希釈混練分散処理部とし、下流側段の希釈混練分散処理部は前記液状希釈剤として液状の二次希釈剤を投入するための二次希釈剤投入部を有し、該二次希釈剤投入部から投入される二次希釈剤と前記一次希釈混練分散処理部から供給される前記一次希釈物とを混練するとともに相互に分散させて前記電極合剤含有組成物スラリーを得るための二次希釈混練分散処理部とするのである。
また、この場合、前記一次希釈混練分散処理部における前記一次希釈剤投入部は、該一次希釈混練分散処理部において前記硬練混練分散処理部にもっとも近く配置されている前記回転円盤が嵌挿されている液注部シリンダーに設け、前記二次希釈混練分散処理部における前記二次希釈剤投入部は、該二次希釈混練分散処理部において前記一次希釈混練分散処理部にもっとも近く配置されている前記回転円盤が嵌挿されている液注部シリンダーに設ける。
For example, it can be provided in two stages, in which case it can be provided as follows, for example.
That is, the upstream-stage dilution kneading and dispersing unit in the same direction as the battery material feeding direction in the supply unit has a primary diluent charging unit for charging a liquid primary diluent as the liquid diluent. A primary dilution kneading dispersion process for kneading the primary diluent introduced from the diluent charging section and the kneaded kneaded dispersion supplied from the kneading kneading dispersion processing section and mutually dispersing them to obtain a primary dilution and parts, dilution kneading dispersion treatment of the downstream stage has a secondary diluent introduction part for introducing secondary diluent liquid as the liquid diluent is introduced from the secondary diluent introduction part A secondary dilution kneading dispersion processing unit for kneading and dispersing the secondary diluent and the primary dilution supplied from the primary dilution kneading dispersion processing unit to obtain the electrode mixture-containing composition slurry; To do.
Further, in this case, the primary diluent charging section in the primary dilution kneading dispersion processing section is fitted with the rotating disk arranged closest to the kneading kneading dispersion processing section in the primary dilution kneading dispersion processing section. The secondary diluent charging unit in the secondary dilution kneading and dispersing unit is disposed closest to the primary dilution kneading and dispersing unit in the secondary dilution kneading and dispersing unit. It is provided in a liquid injection part cylinder into which the rotating disk is inserted.

このように希釈処理を行う希釈混練分散処理部として一次希釈混練分散処理部及び二次希釈混練処理部を採用した装置を用いる二次電池用の電極合剤含有組成物スラリーの製造方法の例として次のものを挙げることができる。   As an example of a method for producing an electrode mixture-containing composition slurry for a secondary battery using an apparatus that employs a primary dilution kneading dispersion processing section and a secondary dilution kneading processing section as a dilution kneading dispersion processing section that performs dilution processing in this way. The following can be mentioned.

二次電池用の電極合剤含有組成物スラリーの連続製造装置において前記供給部から連続して延びる前記連続回転軸を回転させて該連続回転軸に支持された回転円盤を回転させつつ、前記粉体の電池材料として粉体電極活物質100部に対し粉体の添加剤である導電助剤及び導電助剤以外の添加剤から選ばれた粉体添加剤を0.05部から15部の範囲の割合で配合した粉体電池材料を前記供給部により連続的に前記メカノケミカル処理部へ供給し、該メカノケミカル処理部において前記供給部から供給されてくる該電池材料にメカノケミカル処理を施し、ひき続き該メカノケミカル処理部で得られたメカノケミカル処理物を前記硬練混練分散処理部へ供給し、該硬練混練分散処理部において前記バインダー投入部から液状のバインダーを0.05部から50部の範囲の割合で投入し、該バインダーと前記メカノケミカル処理物に混練分散処理を施し、該硬練混練分散処理部で得られた硬練混練物をひき続き前記一次希釈混練分散処理部へ供給し、該一次希釈混練分散処理部において前記一次希釈剤として液状希釈バインダーを10部〜60部の範囲の割合で前記一次希釈剤投入部から投入し、該液状希釈バインダーと前記硬練混練分散処理部から供給された硬練混練物に一次希釈混練分散処理を施し、該一次希釈混練分散処理部で得られた一次希釈物をひき続き前記二次希釈混練分散処理部へ供給し、該二次希釈混練分散処理部において前記二次希釈剤として溶剤を10部〜60部の範囲の割合で前記二次希釈剤投入部から投入し、該溶剤と前記一次希釈混練分散処理部から供給された一次希釈物に二次希釈混練分散処理を施して固形分濃度が30%〜90%になるように配合された二次電池用の電極合剤含有組成物スラリーを連続的に得る二次電池用の電極合剤含有組成物スラリーの連続製造方法である。   In a continuous production apparatus for an electrode mixture-containing composition slurry for a secondary battery, while rotating the continuous rotating shaft continuously extending from the supply unit and rotating a rotating disk supported on the continuous rotating shaft, the powder A powder additive selected from a conductive additive which is a powder additive and an additive other than the conductive additive with respect to 100 parts of the powder electrode active material as a battery material of the body is in the range of 0.05 part to 15 parts. Is continuously supplied to the mechanochemical processing unit by the supply unit, and mechanochemical processing is performed on the battery material supplied from the supply unit in the mechanochemical processing unit, Subsequently, the mechanochemically processed product obtained in the mechanochemical processing section is supplied to the kneading and kneading dispersion processing section, and in the kneading and kneading dispersion processing section, the liquid binder is supplied from the binder charging section to 0. 5 parts to 50 parts is added, the binder and the mechanochemically treated product are kneaded and dispersed, and the kneaded and kneaded product obtained in the kneaded and kneaded and dispersed part is continuously added to the primary dilution kneaded product. Supplying to the dispersion processing section, in the primary dilution kneading dispersion processing section, the liquid diluent binder as the primary diluent at a ratio in the range of 10 to 60 parts from the primary diluent charging section, the liquid diluted binder and the above The kneaded kneaded product supplied from the kneaded kneading and dispersing unit is subjected to primary dilution kneading and dispersing treatment, and the primary dilution obtained in the primary dilution kneading and dispersing unit is continuously supplied to the secondary dilution kneading and dispersing unit. In the secondary dilution kneading dispersion processing section, a solvent as the secondary diluent is charged from the secondary diluent charging section at a ratio in the range of 10 to 60 parts, and the solvent and the primary dilution kneading dispersion processing section Supplied from Secondary battery for continuously obtaining an electrode mixture-containing composition slurry for a secondary battery obtained by subjecting the primary dilution to a secondary dilution kneading dispersion treatment so as to have a solid content concentration of 30% to 90% It is a continuous manufacturing method of the electrode mixture containing composition slurry for use.

メカノケミカル処理において導電性の助剤(導電助剤)又は導電助剤以外の添加剤から選ばれた粉体添加剤の量を0.05部〜15部とするのは、0.05部未満では電池の導通が得られない恐れがあり、15部を超えてくると二次電池の主要材である活物質の割合が減少し、電池容量が小となり、電池性能が低下してくるからである。   In the mechanochemical treatment, the amount of the powder additive selected from the conductive auxiliary agent (conductive auxiliary agent) or additives other than the conductive auxiliary agent is 0.05 to 15 parts. In this case, there is a possibility that the battery cannot be connected. If the amount exceeds 15 parts, the ratio of the active material as the main material of the secondary battery decreases, the battery capacity becomes small, and the battery performance decreases. is there.

硬練混練分散処理において、バインダーの割合を0.05部から50部とするのは、0.05部未満では材料が硬練混練物、換言すれば粘土状物にならず、混練操作の効率が低下するからであり、50部を超えてくると、スラリー粘度の低下による剪断力伝達不良、それによる混練分散処理の効率低下が生じてくるからである。   In the kneading and kneading dispersion treatment, the binder ratio is set to 0.05 part to 50 parts because if the amount is less than 0.05 part, the material does not become a kneaded kneaded material, in other words, a clay-like material, and the efficiency of the kneading operation is reduced. This is because if the amount exceeds 50 parts, shearing force transmission failure due to a decrease in slurry viscosity, resulting in a decrease in efficiency of the kneading and dispersing treatment.

また、一次希釈混練分散処理において希釈バインダーの割合を10部〜60部とするのは、10部未満では活物質と活物質、或いは活物質とスラリーを塗布する対象材(一般的には集電体)の結着性が乏しくなるからであり、60部を超えてくると、電池性能に直接関係のないバインダーの割合が増えてくるからである。   Also, in the primary dilution kneading dispersion treatment, the ratio of the diluted binder is 10 parts to 60 parts because if it is less than 10 parts, the active material and the active material or the target material to which the active material and the slurry are applied (generally a current collector) This is because the binding property of the body becomes poor, and when it exceeds 60 parts, the proportion of the binder that is not directly related to the battery performance increases.

二次希釈混練分散処理において溶剤の割合を10部〜60部とするのは、10部未満ではスラリー粘度が高くなることによる塗工不良が発生し、60部を超えてくると、最終的に揮発させる溶剤の量が増え過ぎるからである。 かくして、最終的に得られる電極合剤含有組成物スラリーにおいては固形分濃度が30%〜90%になるよう配合された状態となる。この固形分濃度のスラリーを塗工処理に供することができる。   In the secondary dilution kneading and dispersing treatment, the solvent ratio is 10 parts to 60 parts. If less than 10 parts, poor coating due to an increase in slurry viscosity occurs. This is because the amount of the solvent to be volatilized increases too much. Thus, the electrode mixture-containing composition slurry finally obtained is in a state where the solid content concentration is 30% to 90%. This solid content slurry can be subjected to a coating treatment.

以上説明したように本発明によると、二次電池形成のための電極合剤含有組成物スラリー塗布対象材への塗布工程に供することができる均質な電極合剤含有組成物スラリーを少なくとも粉体の電極活物質を含む粉体電池材料を出発原料として目的とする電極合剤含有組成物スラリーまで一貫して連続的に再現性良好に製造することができる二次電池用の電極合剤含有組成物スラリーの連続製造装置及び連続製造方法を提供することができる。   As described above, according to the present invention, at least a homogeneous electrode mixture-containing composition slurry that can be subjected to an application process to an electrode mixture-containing composition slurry application target material for forming a secondary battery is at least in powder form.

後述する硬練混練分散処理部3の液注部回転円盤25の上流側の側面もメカノケミカル処理部2の一部である。
In this embodiment, the mechanochemical processing unit 2 includes two annular fixed disks 21, an annular kneading cylinder 22 sandwiched between the fixed disks 21, the fixed disk 21, and the fixed disk 21. And a rotating disk 23 arranged to do so.
The side surface on the upstream side of the liquid injection part rotating disk 25 of the kneading and kneading dispersion processing part 3 described later is also a part of the mechanochemical processing part 2.

メカノケミカル処理部2は以上説明したものに限定されない。もう少し一般的に言えば、2枚以上の環状の固定円盤21と、これら固定円盤21間に挟持された状態で固定円盤21と交互に配置される1枚以上の環状の混練シリンダー22と、表裏面(図1において右側の面及び左側の面、換言すれば、材料送り方向において上流側の面及び下流側の面)が固定円盤21と対向した状態で混練シリンダー21と中心軸線を同じくして配置される1枚以上の回転円盤23とを含むものである。   The mechanochemical processing unit 2 is not limited to the one described above.

回転円盤23は、外径寸法が混練シリンダー22の内径寸法より僅かに小さく設定されているとともに、中間スクリュー24は、外径寸法が固定円盤21の内径寸法より僅かに小さく設定され、これによって回転円盤23及び中間スクリュー24は、回転軸200に交互に外嵌された状態で、外周面が混練シリンダー22及び固定円盤21の内周面に対して原料が通過し得る隙間を提供しつつそれぞれ対向している。 The rotary disk 23 is set to have an outer diameter dimension slightly smaller than the inner diameter dimension of the kneading cylinder 22, and the intermediate screw 24 is set to have an outer diameter dimension slightly smaller than the inner diameter dimension of the fixed disk 21, thereby rotating.

ケーシング11内に導入された原料は、スパイラルロッド12の駆動回転によるスパイラルフイン122の回転によって順次下流側のメカノケミカル処理部2へ向けて搬送される。

メカノケミカル処理部2等における固定円盤とそれに対向する回転円盤との間に形成される前記剪断分散処理域ついてさらに説明する。
メカノケミカル処理部2における上流側の固定円盤21の下流側の側面208(図2参照)とそれに対向する回転円盤23の上流側の側面201(図3参照)とで、それらの隙間に入り込む処理対象材料に剪断及び分散処理を施す剪断分散処理域が形成されている。
The shear dispersion treatment area formed between the fixed disk and the rotating disk facing the fixed disk in the mechanochemical processing unit 2 will be further described.
A process in which the downstream side surface 208 (see FIG. 2) of the upstream fixed disk 21 and the upstream side surface 201 (see FIG. 3) of the rotating disk 23 facing the mechanochemical processing unit 2 enter the gap. A shear dispersion treatment area for subjecting the target material to shear and dispersion treatment is formed.

この剪断分散処理域は固定円盤21の下流側の側面208に形成された複数の凹所208’(図2参照)とこれに対向する回転円盤23の上流側の側面201に形成された複数の凹所201’(図3参照)とを含んでいる。   The shear dispersion treatment area includes a plurality of recesses 208 ′ (see FIG. 2) formed on the downstream side surface 208 of the fixed disk 21 and a plurality of upstream side surfaces 201 of the rotating disk 23 facing the recesses 208 ′. And a recess 201 '(see FIG. 3).

この剪断分散処理域によると、固定円盤21の下流側面208の凹所208’及び回転円盤23の上流側の側面201の凹所201’に捕捉される材料が固定円盤21に対する回転円盤23の回転に伴って凹所内に旋回流が形成されつつ移動する際に剪断力を受けるとともに分散せしめられる。
環状固定円盤21の凹所208’の縁と回転円盤23の凹所201’の縁とは、回転円盤23の回転に伴ってそれら縁がすれ違うときに、処理対象材料が回転円盤23の円周側へ送られるように、円盤半径方向に対する延び方向角度(固定円盤の凹所縁と回転円盤の凹所縁の延び方向の相対的角度)が調整されている。
図示を省略しているが、回転円盤23の外周部には処理対象材料を送るスクリュー様の送り部材が形成されている。このスクリュー様の送り部材は他の回転部材にも設けられている。
According to this shear dispersion processing region, the material trapped in the recess 208 ′ on the downstream side surface 208 of the fixed disk 21 and the recess 201 ′ on the upstream side surface 201 of the rotating disk 23 rotates the rotating disk 23 with respect to the fixed disk 21. Along with this, when a swirl flow is formed in the recess, the shearing force is received and dispersed.
When the edge of the recess 208 ′ of the annular fixed disk 21 and the edge of the recess 201 ′ of the rotating disk 23 pass with each other as the rotating disk 23 rotates, the material to be processed becomes the circumference of the rotating disk 23. The extending direction angle with respect to the radial direction of the disk (relative angle of the extending direction of the recessed edge of the fixed disk and the recessed edge of the rotating disk) is adjusted so as to be sent to the side.
Although not shown, a screw-like feeding member for feeding the material to be processed is formed on the outer peripheral portion of the rotating disk 23. This screw-like feed member is also provided on other rotating members.

また、メカノケミカル処理部2における下流側の固定円盤21の上流側の側面207(図2参照)とそれに対向する回転円盤23の下流側の側面202(図3参照)とで、それらの隙間に入り込む処理対象材料に剪断及び分散処理を施す剪断分散処理域が形成されている。   Further, in the gap between the upstream side surface 207 (see FIG. 2) of the downstream fixed disk 21 and the downstream side surface 202 (see FIG. 3) of the rotating disk 23 facing the mechanochemical processing unit 2.

この剪断分散処理域は下流側固定円盤21の上流側の側面207に形成された複数の凹所207’(図2参照)とこれに対向する回転円盤23の下流側の側面202に形成された複数の凹所202’(図3参照)とを含んでいる。   This shear dispersion treatment area was formed on a plurality of recesses 207 ′ (see FIG. 2) formed on the upstream side surface 207 of the downstream fixed disk 21 and on the downstream side surface 202 of the rotating disk 23 facing this. And a plurality of recesses 202 '(see FIG. 3).

かくして、下流側固定円盤21の上流側の側面207の凹所207’及び回転円盤23の下流側の側面202の凹所202’に捕捉される材料は、回転円盤23の固定円盤21に対する回転に伴い、剪断及び分散処理を受ける。
下流側固定円盤21の上流側側面の凹所207’の縁と回転円盤23の下流側側面の凹所202’の縁とは、回転円盤23の回転に伴ってそれら縁がすれ違うときに、処理対象材料が回転円盤23の回転軸側へ送られるように、円盤半径方向に対する延び方向角度(固定円盤の凹所縁と回転円盤の凹所縁の延び方向の相対的角度)が調整されている。
Thus, the material trapped in the recess 207 ′ on the upstream side surface 207 of the downstream fixed disk 21 and the recess 202 ′ on the downstream side surface 202 of the rotating disk 23 is rotated by the rotation of the rotating disk 23 relative to the fixed disk 21. As a result, it undergoes shearing and dispersion treatment.
When the edge of the recess 207 ′ on the upstream side surface of the downstream fixed disk 21 and the edge of the recess 202 ′ on the downstream side surface of the rotating disk 23 pass with each other as the rotating disk 23 rotates, processing is performed. The extending direction angle with respect to the radial direction of the disk (relative angle between the extending direction of the recessed edge of the fixed disk and the recessed edge of the rotating disk) is adjusted so that the target material is sent to the rotating shaft side of the rotating disk 23.

さらに、下流側の固定円盤21の下流側の側面208(図2参照)とそれに対向す液注部回転円盤25の上流側の側面201(図3参照)とで、それらの隙間に入り込む処理対象材料に剪断及び分散処理を施す剪断分散処理域が形成されている。   Furthermore, the downstream side 208 (see FIG. 2) of the stationary disk 21 on the downstream side and the upstream side 201 (see FIG. 3) on the upstream side of the liquid injection part rotating disk 25 opposite to the downstream side 208 are processed. A shear dispersion treatment zone is formed for subjecting the material to shear and dispersion treatment.

この剪断分散処理域は下流側固定円盤21の下流側の側面208に形成された複数の凹所208’(図2参照)とこれに対向する回転円盤25の上流側の側面201に形成された複数の凹所201’(図3参照)とを含んでいる。   This shear dispersion treatment area was formed on a plurality of recesses 208 ′ (see FIG. 2) formed on the downstream side surface 208 of the downstream fixed disk 21 and on the upstream side surface 201 of the rotating disk 25 facing this. A plurality of recesses 201 '(see FIG. 3).

かくして、下流側固定円盤21の下流側の側面208の凹所208’及び回転円盤25の上流側側面の凹所201’(図3参照)に捕捉される材料は剪断、分散処理を受ける。   Thus, the material trapped in the recess 208 ′ on the downstream side surface 208 of the downstream fixed disk 21 and the recess 201 ′ (see FIG. 3) on the upstream side surface of the rotating disk 25 is subjected to a shearing and dispersion treatment.

Also in the kneading process, the diluting binder and the kneaded kneaded material pass through the shear dispersion treatment area in the processing section, so that they are kneaded uniformly and dispersed uniformly.

この一次希釈物はひき続き二次希釈混練分散処理部5へ送られ、該処理部で予め定めた配合割合となるように供給される溶剤とともに混練される。該混練処理においても溶剤と一次希釈物とが該処理部における剪断分散処理域を通過することでそれらは均一状に混練されるとともに相互に均一状に分散される。
かくして、均質な、塗布工程に供することができる適度の粘度の二次電池用の電極合剤含有組成物スラリーが品質再現性良好に連続的に得られる。
This primary dilution is subsequently sent to the secondary dilution kneading dispersion processing section 5 where it is kneaded with the solvent supplied so as to have a predetermined blending ratio. Also in the kneading treatment, the solvent and the primary dilution pass through the shear dispersion treatment zone in the treatment section, so that they are uniformly kneaded and uniformly dispersed with each other.

<Comparative Example 1>
Lithium ion secondary battery material lithium manganate (average particle diameter: 5 μm) and conductive auxiliary agent acetylene black using a planetary desper (PVM100-2D) manufactured by Iwata Tekko Co., Ltd. 95 parts of lithium acid: 5.75 parts of PVDF (solid content concentration 8%) as a liquid raw material is added to 5 parts of acetylene black to obtain a solid content concentration of 95%, and the low-speed shaft rotation speed of PVM100-2D is set to 20 rotations per minute And kneading and kneading for 1 hour.

実施例1と比較例1を比較する。
1.塗工量を22.1mg/cm2 に換算した場合、実施例1の合材厚は103μmとなる。比較例1の合材厚に対して実施例1は約93%であることから合材の充填密度が約7%上昇していることがわかる。
2.密度の測定においても比較例1が2.0、実施例1が2.16であることから圧密度が約8%上昇していることがわかる。
充填密度及び圧密度の上昇は電池容量の上昇に寄与する。
3.塗工面の平滑性は作業効率の効率化に寄与する。塗工面がひび割れを起こす塗料の物性では塗工速度をさらに遅くしなければならないが、平滑性が保たれている場合は塗工速度をさらに早く出来る可能性が有る。
Example 1 and Comparative Example 1 are compared.
1. When the coating amount is converted to 22.1 mg / cm 2 , the composite thickness of Example 1 is 103 μm. Since Example 1 is about 93% with respect to the composite material thickness of Comparative Example 1, it can be seen that the packing density of the composite material is increased by about 7%.
2. Also in the measurement of density, it can be understood that the pressure density is increased by about 8% because Comparative Example 1 is 2.0 and Example 1 is 2.16.
The increase in packing density and pressure density contributes to an increase in battery capacity.
3. The smoothness of the coated surface contributes to the improvement of work efficiency. Although the coating speed has to be further slowed down for the physical properties of the paint that causes the coating surface to crack, if the smoothness is maintained, there is a possibility that the coating speed can be further increased.
