Description

本発明は、２Ｖ（ボルト）系制御弁式鉛蓄電池に関するものである。   The present invention relates to a 2V (volt) control valve type lead storage battery.

鉛蓄電池は、鉛の一部が酸化された鉛粉と水と希硫酸とを主成分とし、これに必要に応じて添加物を添加して練合し、得られたペーストを鋳造格子体や連続多孔格子体に塗着し、乾燥させたペースト式極板が広く用いられている。この極板は、更にセパレータ（隔離板）と組み合わせて極板群に構成され、電槽に組み込まれた後、希硫酸を加えて化成充電するか、化成充電後に電槽内に組み込むことによって、電池の性能が与えられる。   A lead storage battery is composed mainly of lead powder in which a part of lead is oxidized, water and dilute sulfuric acid, and if necessary, additives are added and kneaded. Paste electrode plates coated on a continuous porous lattice and dried are widely used. This electrode plate is further combined with a separator (separator plate) to form an electrode plate group, and after being incorporated in the battery case, it is formed by adding dilute sulfuric acid, or it is incorporated into the battery case after chemical charge, Battery performance is given.

ところで、鉛蓄電池の主な用途の一つとして、自動車エンジンの始動がある。これは、大電流放電によりエンジン内にスパークを発生させるというものであるが、この時の放電電圧が低いまたは放電時間が短いと、エンジンが始動しないという不具合が生じる。   By the way, one of the main uses of lead-acid batteries is to start automobile engines. This is to generate a spark in the engine by a large current discharge. However, if the discharge voltage at this time is low or the discharge time is short, the engine does not start.

この不具合を解消するため、より始動性の高い巻回型制御弁式鉛蓄電池が提案されている（例えば、特許文献１参照。）。   In order to eliminate this problem, a wound type control valve type lead storage battery with higher startability has been proposed (for example, see Patent Document 1).

この巻回型制御弁式鉛蓄電池を自動車エンジンの始動用として用いる場合、通常直列に接続した６個組みの組電池として用いる。   When this wound-type control valve type lead-acid battery is used for starting an automobile engine, it is usually used as a six-piece assembled battery connected in series.

このような自動車エンジンの始動用として用いる組電池は、一般にエンジンルーム内に設置するが、電池から発生する水素が引火するのを防ぐため、微孔を有する防爆フィルタを具備している。
米国特許第５６７７０７８号明細書（図３） Such an assembled battery used for starting an automobile engine is generally installed in an engine room, and is provided with an explosion-proof filter having micropores in order to prevent hydrogen generated from the battery from igniting.
US Pat. No. 5,677,078 (FIG. 3)

従来の巻回型制御弁式鉛蓄電池の組電池においては、モノブロック電槽の蓋部に防爆フィルタを具備しているが、それぞれ独立した２Ｖ電池を６個組み合わせて電槽に組み込んで組電池を構成する場合、振動等に対する耐久性の面で密閉を保持することが困難になる問題点があった。   A conventional battery pack of a wound type control valve type lead-acid battery has an explosion-proof filter in the lid of the monoblock battery case, but the battery pack is formed by combining six independent 2V batteries into the battery case. However, it is difficult to maintain a hermetic seal in terms of durability against vibration and the like.

本発明の目的は、組電池を構成する場合、簡易な開放構造の電槽でモノブロック化することができる２Ｖ系制御弁式鉛蓄電池を得ることにある。   An object of the present invention is to obtain a 2V control valve-type lead storage battery that can be monoblocked by a battery case having a simple open structure when an assembled battery is formed.

本発明の他の目的は、組電池を構成する場合、振動等に対する耐久性の面で密閉を保持することができる２Ｖ系制御弁式鉛蓄電池を得ることにある。   Another object of the present invention is to obtain a 2V control valve-type lead-acid battery that can maintain hermeticity in terms of durability against vibration or the like when an assembled battery is configured.

本発明は、電池内部の圧力を放出するためのゴム弁と、このゴム弁の抜け防止のための押え板とを具備する２Ｖ系制御弁式鉛蓄電池を対象とする。   The present invention is directed to a 2V control valve type lead storage battery including a rubber valve for releasing the pressure inside the battery and a presser plate for preventing the rubber valve from coming off.

本発明に係る２Ｖ系制御弁式鉛蓄電池では、押え板として通気用の微孔を有する防爆フィルタが用いられていることを特徴とする。   The 2V control valve type lead-acid battery according to the present invention is characterized in that an explosion-proof filter having a ventilation microhole is used as a presser plate.

また、本発明に係る２Ｖ系制御弁式鉛蓄電池では、押え板の排気孔の下でゴム弁の上には通気用の微孔を有する防爆フィルタが配置され、電池内部と外部の通気は防爆フィルタと排気孔を経て行われるようになっていることを特徴とする。   Further, in the 2V control valve type lead-acid battery according to the present invention, an explosion-proof filter having a micro-hole for ventilation is disposed under the exhaust hole of the holding plate and above the rubber valve, and the ventilation inside and outside the battery is explosion-proof. It is characterized by being performed through a filter and an exhaust hole.

この場合、防爆フィルタの上部と押え板の下部との間に空隙が設けられていることが好ましい。   In this case, it is preferable that a gap is provided between the upper part of the explosion-proof filter and the lower part of the presser plate.

本発明に係る２Ｖ系制御弁式鉛蓄電池では、押え板として通気用の微孔を有する防爆フィルタを用いたので、この電池を複数用いて電槽内にセットして組電池を構成する場合、簡易な開放構造の電槽でモノブロック化することができる。   In the 2V system control valve type lead storage battery according to the present invention, since an explosion-proof filter having a microscopic hole for ventilation is used as a holding plate, when a plurality of these batteries are used and set in a battery case to constitute an assembled battery, It can be monoblocked with a battery case with a simple open structure.

また、本発明に係る２Ｖ系制御弁式鉛蓄電池では、押え板の排気孔の下でゴム弁の上には通気用の微孔を有する防爆フィルタが配置され、電池内部と外部の通気は防爆フィルタと排気孔を経て行われるようになっているので、防爆フィルタの上の押え板の存在により、防爆フィルタにごみや水滴が付くことによる目詰まりを防止することができる。また、防爆フィルタが２Ｖ電池に組み込まれているので、この電池を複数用いて電槽内にセットして組電池を構成する場合、簡易な開放構造の電槽でモノブロック化することができる。   Further, in the 2V control valve type lead-acid battery according to the present invention, an explosion-proof filter having a micro-hole for ventilation is disposed under the exhaust hole of the holding plate and above the rubber valve, and the ventilation inside and outside the battery is explosion-proof. Since it is performed through the filter and the exhaust hole, the presence of the holding plate on the explosion-proof filter can prevent clogging due to dust and water droplets on the explosion-proof filter. Further, since the explosion-proof filter is incorporated in the 2V battery, when a plurality of these batteries are used and set in the battery case to form an assembled battery, the battery can be monoblocked with a battery case having a simple open structure.

この場合、防爆フィルタの上部と押え板の下部との間に空隙が設けられていると、防爆フィルタが外気に触れる面積が大きくなり、通気効率を上げることができる。   In this case, if an air gap is provided between the upper part of the explosion-proof filter and the lower part of the presser plate, the area where the explosion-proof filter comes into contact with the outside air increases, and the ventilation efficiency can be increased.

以下、本発明に係る２Ｖ系制御弁式鉛蓄電池の実施の形態の一例を図１（Ａ）（Ｂ）乃至図３を参照して詳細に説明する。図１（Ａ）（Ｂ）は本例の２Ｖ系制御弁式鉛蓄電池の平面図及び側面図、図２は図１（Ａ）のＡ−Ａ´線断面図、図３は図１（Ａ）のＢ−Ｂ´線断面図である。   Hereinafter, an example of an embodiment of a 2V control valve type lead-acid battery according to the present invention will be described in detail with reference to FIGS. 1A and 1B are a plan view and a side view of a 2V control valve type lead-acid battery of this example, FIG. 2 is a cross-sectional view taken along the line AA ′ of FIG. 1A, and FIG.

A negative electrode active material paste was prepared, and 240.0 g of this negative electrode active material paste was filled in a current collector made of a lattice, and then left to age for 18 hours in a temperature of 50 ° C. and a humidity of 95%, and then a temperature of 25 An unformed negative electrode plate was prepared by leaving it to stand in a temperature of 40 ° C. for 2 hours and drying.

正極板は次のようにして作成した。後述する正極活物質ペーストの混練を行う混練釜として、冷却できるものを用いて混練の間温度を一定に保って行った。即ち、正極板は、鉛粉と、該鉛粉に対して０．０１質量％の硫酸ナトリウム及びカットファイバーを添加し、該鉛粉に対して１３質量％の希硫酸（比重１．２６：２ｏ℃）と、該鉛粉に対して１２質量％の水とを混練して正極活物質ペーストを作成した。次に、この正極活物質ペースト２００．０ｇを鋳造格子体からなる集電体に充填してから、温度５０℃、湿度９５％中に１８時間放置して熟成した後、温度２５℃、湿度４０％中に２時間放置し、乾燥して未化成正極板を作成した。   The positive electrode plate was prepared as follows. As a kneading pot for kneading the positive electrode active material paste described later, a coolable one was used to keep the temperature constant during kneading. That is, the positive electrode plate was prepared by adding lead powder, 0.01% by weight sodium sulfate and cut fiber to the lead powder, and 13% by weight dilute sulfuric acid (specific gravity 1.26: 2o with respect to the lead powder). ° C) and 12% by mass of water with respect to the lead powder to prepare a positive electrode active material paste. Next, 200.0 g of this positive electrode active material paste was filled into a current collector made of a cast grid, and then left to age for 18 hours in a temperature of 50 ° C. and a humidity of 95%, and then a temperature of 25 ° C. and a humidity of 40 % For 2 hours, and dried to prepare an unformed positive electrode plate.

このように作成した未化成負極板と未化成正極板をガラス繊維からなるセパレータを介して巻回し、図２に示すような円柱状の極板群１を得た。この極板群１を、図１（Ａ）（Ｂ）及び図２に示すように、有底円筒状の電槽２の中に配置し、また電槽２内には電解液を注液し、電槽２の開口部は、図１（Ａ）（Ｂ）及び図３に示すように、上蓋３で密封した。極板群１の負極板と正極板はその集電体４，５をストラップ６，７で接続し、各ストラップ６，７の極柱８，９は上蓋３を貫通し、上蓋３の上面の接続バー１０，１１に電気的に接続され、接続バー１０，１１には上蓋３上の所要の位置に負極端子１２と正極端子１３が立設されている。   The unformed negative electrode plate and the unformed positive plate prepared in this way were wound through a separator made of glass fiber to obtain a cylindrical electrode plate group 1 as shown in FIG. As shown in FIGS. 1 (A), 1 (B) and 2, the electrode plate group 1 is placed in a bottomed cylindrical battery case 2, and an electrolytic solution is injected into the battery case 2. The opening of the battery case 2 was sealed with an upper lid 3 as shown in FIGS. The negative electrode plate and the positive electrode plate of the electrode plate group 1 have their current collectors 4, 5 connected by straps 6, 7, and the pole columns 8, 9 of each strap 6, 7 penetrate the upper lid 3. The connection bars 10 and 11 are electrically connected to each other, and the connection bars 10 and 11 are provided with a negative electrode terminal 12 and a positive electrode terminal 13 standing at predetermined positions on the upper lid 3.

また、上蓋３には凹部１４が設けられ、凹部１４の底部１５には弁孔１６が貫通され、この弁孔１６を包囲して円筒状に弁座１７が立設され、この弁座１７の上部にはキャップ状のゴム弁１８が嵌められ、このゴム弁１８上には通気用の微孔を有する防爆フィルタ１９が配置され、この防爆フィルタ１９の上には押え板２０が配置されて、凹部１４の入口の段部１４ａに載せられて固定され、防爆フィルタ１９に対応する箇所で押え板２０には排気口２１が設けられている。この場合、押え板２０の下面と防爆フィルタ１９の上面との間には、空隙２２が設けられている。この空隙２２は、押え板２０の下面の一部を窪ませて設けられている。かかる状態で、上蓋３の上面の凹部には樹脂２３が充填されている。   Further, the upper lid 3 is provided with a recess 14, and a valve hole 16 is passed through the bottom 15 of the recess 14, and a valve seat 17 is erected in a cylindrical shape surrounding the valve hole 16. A cap-shaped rubber valve 18 is fitted on the upper part, an explosion-proof filter 19 having a microscopic hole for ventilation is disposed on the rubber valve 18, and a presser plate 20 is disposed on the explosion-proof filter 19. The presser plate 20 is provided with an exhaust port 21 at a location corresponding to the explosion-proof filter 19 and mounted on the step 14 a at the entrance of the recess 14. In this case, a gap 22 is provided between the lower surface of the holding plate 20 and the upper surface of the explosion-proof filter 19. The gap 22 is provided by recessing a part of the lower surface of the presser plate 20. In such a state, the resin 23 is filled in the recess on the upper surface of the upper lid 3.

このような２Ｖ系制御弁式鉛蓄電池では、防爆フィルタ１９がこの２Ｖ電池に組み込まれているので、６個組みの組電池を電槽にセットして構成する場合、簡易な開放構造の電槽でモノブロック化することができる。また、防爆フィルタ１９の上に押え板２０があって、この押え板２０には防爆フィルタ１９に対応して排気孔２１が設けられているので、防爆フィルタ１９にごみや水滴が付くことによる目詰まりを防止することができる。また、防爆フィルタ１９の上部と押え板２０の下部との間に空隙２２が設けられているので、防爆フィルタ１９が外気に触れる面積が大きくなり、通気効率を上げることができる。   In such a 2V control valve type lead-acid battery, since the explosion-proof filter 19 is incorporated in the 2V battery, a battery case with a simple open structure is used when a set of six assembled batteries is set in the battery case. Can be monoblocked. In addition, since the holding plate 20 is provided on the explosion-proof filter 19 and the holding plate 20 is provided with an exhaust hole 21 corresponding to the explosion-proof filter 19, an eye is formed when dust or water droplets are attached to the explosion-proof filter 19. Clogging can be prevented. Moreover, since the space | gap 22 is provided between the upper part of the explosion-proof filter 19 and the lower part of the presser plate 20, the area which the explosion-proof filter 19 touches external air becomes large, and it can improve ventilation efficiency.

上記例では、ゴム弁１８と防爆フィルタ１９が押え板２０で押えられた構造であったが、ゴム弁１８の押えを防爆フィルタ１９で行い、この防爆フィルタ１９を上蓋３に固定して、押え板２０を防爆フィルタ１９で兼用させることもできる。   In the above example, the rubber valve 18 and the explosion-proof filter 19 are pressed by the presser plate 20. However, the rubber valve 18 is pressed by the explosion-proof filter 19, and the explosion-proof filter 19 is fixed to the upper lid 3 to press the The plate 20 can also be used as the explosion-proof filter 19.

このような構造の２Ｖ系制御弁式鉛蓄電池でも、この電池を複数用いて電槽内にセットして組電池を構成する場合、簡易な開放構造の電槽でモノブロック化することができる。   Even in a 2V control valve type lead storage battery having such a structure, when a plurality of batteries are used and set in a battery case to form an assembled battery, the battery can be monoblocked with a battery case having a simple open structure.
