摘　　要：阀控式铅酸蓄电池使用一段时间后,实际容量会下降,主要原因是电极上生成了大量Pb SO4粗结晶,简称硫化。Pb SO4粗结晶在充电时无法还原为Pb单质和Pb O2,采用常规的方法难以解决这个问题。脉冲充电法可以使不可逆的Pb SO4粗结晶变为细颗粒,并参与充电反应。本文介绍了脉冲充电法的工作原理,详细地分析了采用脉冲充电法对硫化的铅酸蓄电池进行活化的过程。The actual capacity of VRLAB will decline after using some time,mainly due to generate a lot of crude crystals of lead sulfate on the electrodes,called vulcanization.The crude crystallization of lead sulfate can not be reduced to elemental lead and lead dioxide during charging.Conventional methods are not solve this problem.Pulse charging method can make irreversible lead sulfate crude crystals into fine particles,and participate in the charging reaction.This article describes the working principle of pulse charging method,a detailed analysis of the process of using pulse charging method for lead-acid batteries were vulcanized activated.
