METHOD FOR PRODUCING LEAD ACID BATTERIES

Under constant voltage recharge, as occurs in battery applications, the recharge current drops if the Nernst voltage equals the applied voltage. Therefore, lead acid batteries cannot achieve optimal cycle life or rechargeability. The main reason is the increase of the Nernst voltage due to build-up of the specific gravity of the sulfuric acid, which increases more quickly in the positive electrodethan in the negative electrode. The invention shows that specific alkaline silicates and/or alkaline zeolites act as blocker of the quick increase in sulfuric acid activity in the positive electrode.This is due to the fact that the cavities and alkaline atoms capture the sulphate ions and thereby reduce the sulfuric acid activity. Especially highly agglomerated alkaline aluminum silicates and alkaline aluminum zeolites are of special interest. 在恒电压再充电下，如在电池应用中发生的，如果能斯特电压等于施加的电压，则再充电电流下降。因此，铅酸电池不能实现最佳的循环寿命或可再充电性。主要原因是由于硫酸比重的积累而引起能斯特电压的增加，硫酸在正电极中比在负电极中增加得更快。本发明表明，特定的碱性硅酸盐和/或碱性沸石充当正电极中硫酸活性快速增加的阻断剂。这是由于空穴和碱性原子捕获硫酸根离子，从而降
