産業上の利用分野
本発明は密閉形−蓄電池の特に負極板の構造に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION 3. Detailed Description of the Invention Field of Industrial Application The present invention relates to a sealed storage battery, particularly to the structure of a negative electrode plate.
従来の技術
密閉形鉛蓄電池は、いわゆるポジションフリーとするた
め、およびガス吸収能を良好にするため、電池内の電解
液量を漏液あるいは浴液しない程度に制限しである。In conventional sealed lead-acid batteries, the amount of electrolyte in the battery is limited to a level that does not cause leakage or bath liquid in order to make the battery so-called position-free and to improve gas absorption ability.
このような電池構造であるため、電池を長期間放置する
と電池内の電解液量が減少する。この減少には２つの原
因があり、その１つは放置中に水分が逸散するものと、
自己放電などにより電解液のＳ０４分が極板に固定され
てしまうことによる。Because of this battery structure, if the battery is left for a long period of time, the amount of electrolyte in the battery decreases. There are two causes for this decrease; one is that moisture evaporates during storage;
This is because the S04 portion of the electrolyte is fixed to the electrode plate due to self-discharge or the like.
このような電池内の電解液量の減少は特に負極板で激し
い。Such a decrease in the amount of electrolyte in the battery is particularly severe in the negative electrode plate.
発明が解決しようとする問題点
このような従来構成では保存後（充電状態、あるいは放
電状態）の容１回復性が著しく悪いという欠点があった
。Problems to be Solved by the Invention This conventional configuration has a disadvantage in that the capacity recovery after storage (charged state or discharged state) is extremely poor.
本発明はこのような欠点を解決するもので、電池を長期
間保存した後でも充電回復性を良好にすることを目的と
するものである。The present invention is intended to solve these drawbacks, and aims to improve charge recovery performance even after a battery has been stored for a long period of time.
問題点を解決するだめの手段
この問題点を解決するために本発明は１電解液を非流動

かつ電導性を有した物質、例えば層状カーボン（膨潤性

ある。Means to Solve the Problem In order to solve this problem, the present invention proposes the following: (1) In a lead-acid battery having a structure in which the electrolyte is made non-fluid or contained in a retainer, sulfuric acid as the electrolyte is Contains and holds;
It also includes a negative electrode plate containing a conductive substance, such as layered carbon (swellable graphite).
作用
この構成により、密閉形鉛蓄電池を長期間保存した後で
も、電解質である硫酸が負極板に添加した硫酸含有物質
に保持され、負極板中の電解液の減少が抑制されること
、および長期保存中に自己放電によって生成した不電導
性の硫酸鉛（ＰｂＳ０４）が存在していてもその間に存
在する層状カーボンを通じて充電されやすくなるだめ、
充電回復性が向上することになる。Effect: With this configuration, even after a sealed lead-acid battery is stored for a long period of time, the sulfuric acid that is the electrolyte is retained in the sulfuric acid-containing substance added to the negative electrode plate, suppressing the decrease of the electrolyte in the negative electrode plate, and ensuring long-term storage. Even if non-conductive lead sulfate (PbS04) generated by self-discharge during storage is present, it is likely to be charged through the layered carbon that exists between them.
This results in improved charge recovery.

The recovered capacity was determined by checking and comparing with the capacity before storage.The results are shown in Table 1.

ある。(Hereinafter, blank) Table 1 Effects of the Invention As shown in the examples in Table 1, a battery in which a material containing sulfuric acid and having electrical conductivity, such as layered carbon, is added to the negative electrode plate is It is clear that the capacity recovery property is good even after long-term storage. This effect is due to the presence of a large amount of sulfuric acid in the negative electrode plate and the fact that p is in a passive state.
This is presumed to be due to the fact that even if bso is generated, the conductive carbon is dispersed, making it easier to charge. As a comparative example, even when ordinary carbon, which is not layered carbon, was added to the negative electrode plate, the large effect as in the present invention was not obtained (with addition of 0.3% by weight, the capacity recovery rate after storage was 6%).
1%). From this, the present invention improves capacity recovery after storage due to the synergistic effect of sulfuric acid content and conductivity.
