铅酸蓄电池正极板电化学性能研究

摘要

从电化学角度解析内化成过程充电阶段，研究正极板阻抗变化和极板真实表面积的变化规律。实验结果表明：蓄电池在不断充电化成过程中，传荷阻抗和传质阻抗都不断减小，而正极板活物质的真实表面积不断增大。%We analyze the process of container formation from the perspective of electrochemistry, and study the change of the impedance and the change of the real surface area on the positive plate. The results show that during the process of formation charging, the mass transfer impedance and charge transfer impedance continue to decrease, and the real surface area of the active material of the positive plate increases.
