Abstract

PURPOSE:To delay the generating of short circuit at the upper part of a lead storage battery by making a separator which is kept in contact with a negative plate at the end position so as to have its height taller than the height of other separators which are kept in contact with other negative plates. CONSTITUTION:A separator 6 at the end position, which is kept is contact with a negative plate 2 at the end position of a plate group putting their faces to each other, is made so as to have its height taller than the height of separators 3 which are kept in contact with other negative plates 2, and when the plate group is enclosed into a battery jar 4, a space 7, which is surrounded with the battery jar 4, the separator 6 at the end position and the negative plate 2, is made so as to become larger. Thereby, increasing in the sorption quantity of lead oxide which is deposited by sorption at the upper part of the negative plate 2 of the plate group, the delaying of short circuit generation can be achieved.

Description

【発明の詳細な説明】 産業上の利用分野 本発明は鉛蓄電池の改良（二関するものである。[Detailed description of the invention] Industrial applications The present invention relates to improvements in lead-acid batteries.

従来の技術 従来鉛蓄電池の陽極板１、陰極板２の形状は同一であり

て同じ寸法のものが使用されている。2. Prior Art The shapes of the anode plate 1 and cathode plate 2 of a conventional lead-acid battery are the same, and although the separator 3 is larger than these plates, they all have the same dimensions.

生じる。Problems to be Solved by the Invention Internal short circuits are a contributing factor to the lifespan of lead-acid batteries, and one of the areas affected is the upper part of the electrode plate group. This occurs because fine lead oxide particles from the anode due to repeated charging and discharging are blown up by convection of the electrolytic solution, etc.9, and are sorbed onto the upper part of the electrode plate group and reduced.

早く多量の酸化鉛微粒子が収着して短絡を促進する。The time until a short circuit changes depending on the amount of sorption. In addition, in lead-acid batteries, when the electrode group is stored in the container 4, both ends of the electrode group are in close contact with the inner wall of the container 4, so the convection of the electrolyte is poor, and the electrode group ends A large amount of lead oxide fine particles are adsorbed earlier than in parts other than the ends, promoting short circuiting.

なお５はガラスマットである。Note that 5 is a glass mat.

問題点を解決するための手段 本発明は上記の如き欠点を除去するもので、極板群の端

ているセパレータよりも高くする。Means for Solving the Problems The present invention eliminates the above-mentioned drawbacks by making the separator that is in contact with the end cathode plate of the electrode plate group higher than the other cathode plates: the separators that are in contact with each other.

作用 極板群端部陰極板上部と、電槽内壁面との間の酸化鉛微
粒子の収着量が増加するので、上部短絡の発生を遅延し
得る。Since the amount of lead oxide fine particles sorbed between the upper part of the cathode plate at the end of the working electrode plate group and the inner wall surface of the battery case increases, the occurrence of an upper short circuit can be delayed.

２上部に収着する酸化鉛の収着量は増加する。Example: The end separator 6 that abuts the cathode plate 2 at the end of the electrode plate group is made 5 fins higher than the separator 3 that abuts the other cathode plate 2, and the electrode plate group is placed in the battery case 4. When stored, battery case 4
The space 7 surrounded by the end separator 6 and the cathode plate 2 is enlarged. By doing so, the amount of lead oxide sorbed onto the upper part of the end cathode plate 2 of the electrode plate group increases.

従って、短絡の発生を遅延ならしめ得る。Therefore, the occurrence of a short circuit can be delayed.

The number of cycles in which an upper short circuit occurred (indicated by S) was approximately doubled.
