産業上の利用分野
本発明は鉛蓄電池、とくにその負極板の特性向上のため
の添加剤に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to lead-acid batteries, and particularly to additives for improving the characteristics of the negative electrode plate thereof.
従来の技術
従来の鉛蓄電池用負極板は、鉛あるいは鉛合金を鋳造あ

、この集電体に、主成分が酸化鉛よりなる活物質原料を
塗着、乾燥し、ついで化成して極板としていた。Conventional technology In conventional negative electrode plates for lead-acid batteries, a current collector grid is produced by casting or expanding lead or lead alloy, and this current collector is coated with an active material whose main component is lead oxide. It was coated, dried, and then chemically converted into electrode plates.
ここでの活物質原料は酸化鉛を主体とする鉛粉と硫酸と
水を混合し練合したもので、機械的強度を改善するため
に耐酸性の合成樹脂繊維を添加したも′のである。The active material raw material here is a mixture of lead powder, mainly lead oxide, sulfuric acid, and water, and acid-resistant synthetic resin fibers are added to improve mechanical strength.
またその他の添加剤として、硫酸バリウム、リグニンス
ルホン酸ナトリウムなどがあるのみである○
発明が解決しようとする問題点
しかし、これらの添加剤のみでは近年発展の蓄しい密閉
形の鉛蓄電池、すなわち電解液量が少なく制限された電
池に要求される負極板の親水性および吸液性の向上には
不充分であった。本発明は、この負極板の特性向上を目
的としたものである。Other additives include barium sulfate, sodium ligninsulfonate, etc. Problems to be Solved by the Invention However, these additives alone cannot be used for sealed lead-acid batteries, which have been developed in recent years, that is, electrolytic batteries. This was insufficient to improve the hydrophilicity and liquid absorbency of the negative electrode plate, which is required for batteries with limited liquid volume. The present invention aims to improve the characteristics of this negative electrode plate.
問題点を解決するための手段
本発明は負極板用の活物質ペーストに所定の吸液性の微
粉末の一定量と、この添加剤によって低下する粒子間お
よび活物質と格子界面の導電性を補なうため導電性の微
粉末の一定量を添加し、負極板の親水性、吸液性の向上
を図ったことを特徴としたものである。Means for Solving the Problems The present invention incorporates a certain amount of predetermined liquid-absorbing fine powder into the active material paste for the negative electrode plate, and reduces the conductivity between particles and at the interface between the active material and the lattice, which is reduced by this additive. A certain amount of conductive fine powder is added to compensate for the negative electrode plate's hydrophilicity and liquid absorption.
作用
本発明による負極板は、電解液の吸液性が向上するため
、長期保存中に電解液中の水分が電槽壁を通して大気中
に拡散し減少して、電解液量が所定量より減少した場合
においても、吸液性に優れるためガラスマットから電解
液の供給を受は充分に保持出来る能力を有するものであ
る。Function: Since the negative electrode plate according to the present invention has improved electrolyte absorbability, during long-term storage, water in the electrolyte diffuses into the atmosphere through the container wall and decreases, causing the amount of electrolyte to decrease below a predetermined amount. Even in such cases, the glass mat has the ability to sufficiently retain the electrolyte supplied from the glass mat due to its excellent liquid absorption properties.
このため、長期保存後の問題点の１つである負極板中の
電解液充填率の低下による容量の低下を抑制することが
出来る。Therefore, it is possible to suppress a decrease in capacity due to a decrease in the electrolyte filling rate in the negative electrode plate, which is one of the problems after long-term storage.
