提高铅酸蓄电池循环寿命的研究

Studies on improving the cycling life of lead-acid batteries

通过对不同极板厚度、不同电解液密度的铅酸蓄电池的初期容量、国标循环寿命和不同限压值的恒流限压充电对循环寿命的研究,以及对寿命终止电池的解剖分析,得出结论:适当增加正极板厚度,降低电解液密度,选择最佳的恒流限压充电的限压值能够提高电池的循环寿命。

Based on a series of studies and analysis in regard to the initial capacity, cycling life and charging algorithms for lead-acid bateeries, it was found that the cycling life of lead-acid batteries could bc extended by means of the following approaches： increasing the thickness of positive plate properly, lowering the electrolyte density and selecting the optimum voltage-limit value for charge at constant current and limited voltage.
