【０００１】0001
本考案は、偏平形非水電解液電池に関するものであって、使用される封口ガス ケットに工夫を施すことによって、正極缶の底面に不測の変形を生じなくしたも のである。 The present invention relates to a flat non-aqueous electrolyte battery, and the sealing gas used is By making improvements to the can, we have prevented unexpected deformation from occurring on the bottom of the cathode can. It is.
【０００２】0002
偏平形非水電解液電池の電池構造としては、図４に示したように、封口ガスケ ット１によって密封した負極端子２と正極缶３との密閉空間内に、円板状の負極 ４と正極合剤ペレット５がセパレータ６を介して組み込まれてなる。 As shown in Figure 4, the battery structure of a flat non-aqueous electrolyte battery includes a sealing gasket. A disk-shaped negative electrode is placed in the sealed space between the negative electrode terminal 2 and the positive electrode can 3 sealed by the cutter 1. 4 and positive electrode mixture pellets 5 are assembled via a separator 6.
【０００３】 この種の偏平形非水電解液電池では、封口ガスケット１と正極合剤ペレット５ との間に電解液保持スペースとしての空間を形成することが必要とされ、その空 間が十分ないと、電解液が不足して電池性能に影響することになる。0003 This type of flat nonaqueous electrolyte battery includes a sealing gasket 1 and a positive electrode mixture pellet 5. It is necessary to form a space as an electrolyte holding space between the If there is not enough time, the electrolyte will run out, which will affect battery performance.
【０００４】 このような空間の介在にとって、正極合剤ペレット５を正しい中心位置に置く 作業は細かく調整しながら行い、手数を要していた。そればかりでなく、若しど ちらかに偏芯して載置されたまま正極缶３先端周縁部の封口作業に移ると、偏芯 によって正極合剤ペレット５と封口ガスケット１との間隔が広がった側の正極缶 ３底面に局部的な変形荷重が加わって不測の変形を生じさせることがあった。図 ４の符号７は、かかる変形箇所を示している。0004 Due to the presence of such a space, the positive electrode mixture pellet 5 must be placed at the correct center position. The work was done with detailed adjustments and was time-consuming. Not only that, but also If the positive electrode can 3 is placed slightly eccentric and the sealing work is started on the periphery of the tip, the eccentricity will occur. The positive electrode can on the side where the distance between the positive electrode mixture pellet 5 and the sealing gasket 1 is widened by 3 A local deformation load was applied to the bottom surface, causing unexpected deformation. figure Reference numeral 7 in 4 indicates such a deformed portion.
【０００５】 このような変形は外観を損なうだけでなく、電池性能にバラツキを生じさせる 原因ともなっていた。[0005] Such deformation not only impairs the appearance but also causes variations in battery performance. It was also the cause.
【０００６】[0006]
本考案の目的は、上記のように、正極合剤ペレット５を封口ガスケット１から 或る間隔離して配置することが電解液充填スペースの確保に必要であるのに、正 極合剤ペレット５を正しく位置させるための手段を欠いていたため、偏芯した位 置のまま封口作業に移って正極缶底面に変形を生じさていた従来の欠点を解消す ることにある。 The purpose of the present invention is to move the positive electrode mixture pellet 5 from the sealing gasket 1 as described above. Although it is necessary to isolate the battery for a certain period of time to secure space for filling the electrolyte, Because there was a lack of means to position the polar mixture pellet 5 correctly, it was placed in an eccentric position. Eliminates the conventional drawback of deformation of the bottom surface of the positive electrode can caused by moving on to the sealing work while the container is still in place. There are many things.
【０００７】[0007]
本考案は、封口ガスケットの内周面に複数個の案内突片を突設し、各案内突片 の先端面で作られる円筒面を正極合剤ペレットの円筒面とほぼ一致させるととも に、各案内突片の平らな上面から正極缶当接面に至る高さを正極合剤ペレットの 高さとほぼ等しくなし、上記正極合剤ペレットは上記封口ガスケットの各案内突 片の先端面に沿って配設されてなるものである。 This invention has a plurality of guide protrusions protruding from the inner peripheral surface of the sealing gasket, and each guide protrusion By making the cylindrical surface formed by the tip surface almost coincide with the cylindrical surface of the positive electrode mixture pellet, The height from the flat top surface of each guide protrusion to the contact surface of the positive electrode can is measured by measuring the height of the positive electrode mixture pellet. The positive electrode mixture pellets are approximately equal in height to each guide protrusion of the sealing gasket. It is arranged along the tip surface of the piece.
【０００８】[0008]
封口ガスケットに形成された複数個の案内突片の先端面に沿い正極合剤ペレッ トを納めると、正極合剤ペレットは正しい中心位置に設置される。 Positive electrode mixture pellets are distributed along the tip surfaces of multiple guide protrusions formed on the sealing gasket. The positive electrode mixture pellet is placed in the correct center position.
【０００９】 この複数個の案内突片の容積を加算しても差程大きくないから、案内突片によ って形成される正極合剤ペレットと封口ガスケット内周面との間の空間は、必要 とする電解液保持に十分な容積を確保する。[0009] Even if you add up the volumes of these multiple guide protrusions, the difference is not that large, so the guide protrusions The space between the positive electrode mixture pellet formed by the process and the inner peripheral surface of the sealing gasket is Ensure sufficient volume to hold the electrolyte.
【００１０】0010
図１には、封口ガスケット１によって密封した負極端子２と正極缶３との密閉 空間内に、円板状の負極４と正極合剤ペレット５とがセパレータ６を介して組み 込まれてなる偏平形非水電解液電池が示されている。基本的な電池構造は従来の それと変わらない。 In FIG. 1, a negative electrode terminal 2 and a positive electrode can 3 are sealed with a sealing gasket 1. In the space, a disc-shaped negative electrode 4 and a positive electrode mixture pellet 5 are assembled with a separator 6 interposed therebetween. A flat non-aqueous electrolyte battery is shown. The basic battery structure is conventional It's no different.
【００１１】 しかし、封口ガスケット１については、一部を破断して示した図２の斜視図か らわかるように、負極端子２の端縁部が嵌合される環状溝８を形成すること以外 に、封口ガスケット１内周面に３個の案内突片９を突設形成している。中心に向 く各案内突片９の先端面１０は、正極合剤ペレット５の外径とほぼ等しい円筒面 上にあるように形成されている。[0011] However, regarding the sealing gasket 1, the perspective view of FIG. As can be seen from the figure, except for forming the annular groove 8 into which the edge of the negative electrode terminal 2 is fitted. Three guide protrusions 9 are formed protrudingly on the inner circumferential surface of the sealing gasket 1. towards the center The tip surface 10 of each guide protrusion 9 is a cylindrical surface approximately equal to the outer diameter of the positive electrode mixture pellet 5. It is formed as above.
【００１２】 位置決め機能を発揮する各先端面１０の大きさは、差程大きくなくてよい。従 って複数個の案内突片９の容積を加算しても差程大きくはない。従って、複数個 の案内突片９を形成したから、電解液充填スペースが大きく削減されてしまうと いったことはない。それでも一層の減少を図りたいならば、図示の例の如く、各 案内突片９の形態を断面梯形状として、先端面１０の下側箇所を斜めに削ぎ落し て下方傾斜面１２を形成したり、また、図示するを省略したが、各案内突片９を 断面角柱状とし、下方傾斜面１２箇所も切欠するようにできる。0012 The size of each tip surface 10 that exhibits a positioning function does not have to be very large. subordinate Therefore, even if the volumes of the plurality of guide protrusions 9 are added together, the difference is not that large. Therefore, multiple Since the guide protrusion 9 is formed, the electrolyte filling space is greatly reduced. I've never been there. However, if you want to further reduce the amount, as in the example shown, The guide protrusion 9 has a ladder-like cross section, and the lower part of the tip surface 10 is shaved off diagonally. Although not shown, each guide protrusion 9 may be formed by forming a downwardly inclined surface 12. It can be made into a prismatic cross-section and have 12 cutouts on the downwardly inclined surface.
【００１３】 各案内突片９の平らな上面１１から正極缶３当接面に至る高さＨは、正極合剤 ペレット５の高さとほぼ等しくなす。[0013] The height H from the flat upper surface 11 of each guide protrusion 9 to the contact surface of the positive electrode can 3 is The height should be approximately equal to the height of pellet 5.
【００１４】 上記した封口ガスケット１を使って偏平形非水電解液電池として組立てる工程 を、図３に従って説明する。先ず裏返しにした負極端子２に負極４を圧着し、そ の上にセパレータ６を置き、電解液注入後、負極端子２の端縁部に封口ガスケッ ト１の環状溝８を嵌合して取付ける。封口ガスケット１内周面に突設形成された 各案内突片９の上面１１はセパレータ６に軽く当接する。次に正極合剤ペレット ５を前記３個の案内突片９の先端面１０に沿って納め、セパレータ６上に載置す ると、正極合剤ペレット５は中心位置を占める。つぎに正極缶３を被せ、最後に 正極缶３の先端周縁部分を内方にかしめることで、図１の製品が得られる。[0014] Process of assembling a flat non-aqueous electrolyte battery using the above sealing gasket 1 will be explained according to FIG. First, crimp the negative electrode 4 onto the negative electrode terminal 2 that has been turned over, and then Place the separator 6 on top, and after injecting the electrolyte, put a sealing gasket on the edge of the negative terminal 2. Fit the annular groove 8 of the plate 1 and install. A protrusion is formed on the inner peripheral surface of the sealing gasket 1. The upper surface 11 of each guide protrusion 9 lightly contacts the separator 6. Next, the positive electrode mixture pellet 5 along the tip surfaces 10 of the three guide protrusions 9 and placed on the separator 6. Then, the positive electrode mixture pellet 5 occupies the center position. Next, cover the positive electrode can 3, and finally The product shown in FIG. 1 is obtained by caulking the peripheral edge of the tip of the positive electrode can 3 inward.
【００１５】 封口ガスケット１と正極合剤ペレット５との間には、上記案内突片９によって 空間１３が形成され、電解液保持スペースとして十分な容積たらしめている。[0015] The guide protrusion 9 is provided between the sealing gasket 1 and the positive electrode mixture pellet 5. A space 13 is formed and has a sufficient volume as an electrolyte holding space.
【００１６】[0016]
本考案は、封口ガスケットの内周面に複数個の案内突片を突設して、各案内突 片の先端面で作られる円筒面を上記正極合剤ペレットの円筒面とほぼ一致させた から、封口ガスケットの各案内突片の先端面に沿って正極合剤ペレットを納める ことができ、これによって正極合剤ペレットを中心位置にあらしめるため、正極 缶底面に不測の変形を生じさせていた原因を払拭できる。同時に、封口ガスケッ トと正極合剤ペレットとの間に電解液保持スペースとして十分な空間を形成する ことができる。 This invention has a plurality of guide protrusions protruding from the inner peripheral surface of the sealing gasket, and each guide protrusion The cylindrical surface created by the tip of the piece was made to almost match the cylindrical surface of the above positive electrode mixture pellet. Then, place the positive electrode mixture pellet along the tip of each guide protrusion of the sealing gasket. This allows the positive electrode mixture pellet to be centered in the positive electrode. The cause of unexpected deformation on the bottom of the can can be eliminated. At the same time, the sealing gasket Create a sufficient space between the electrode and the positive electrode mixture pellet to hold the electrolyte. be able to.
【００１７】 また、各案内突片の平らな上面から正極缶当接面に至る高さを正極合剤ペレッ トの高さとほぼ等しくしたから、偏平形非水電解液電池として組み上げた際に、 各案内突片の上面でセパレータの端部を支承し、セパレータに無理な変形をさせ ない真直ぐな展張状態のままで保持されることになる。[0017] In addition, the height from the flat top surface of each guide protrusion to the contact surface of the positive electrode can should be adjusted to the height of the positive electrode mixture pellet. Since the height is approximately equal to the height of the Support the end of the separator on the top surface of each guide protrusion, and prevent the separator from deforming unreasonably. It will be held in a straight and extended state.
