摘要
对三种腐植酸的物理性能、官能团含量、Pb2+吸附量进行了对比,采用循环伏安法研究各腐植酸在充放电过程中的电化学行为,并对其成品铅蓄电池进行充电接受、低温和大电流放电试验,认为腐植酸对铅蓄电池电化学反应活性、充电接受等电化学性能起着重要作用。
In this paper, the comparison of three kinds of humic acid had been studied, including physical performance, content of functional groups and Pb^2＋ adsorbing capacity. The electrochemical behavior of different humic acid in the process of charging and discharging was investigated by cyclic voltammetry（CV）. And the charge acceptance ability, performance of low temperature and large-current discharge of the finished battery were tested, too. The results showed that the additive of humic acid played an important role in the electrochemical performance of lead-acid battery, such as electrochemical activity and charge acceptance.
