摘　　要：通过循环伏安和电镜扫描分析研究了铅酸电池负极放电过程中和不同放电倍率下硫酸铅的特性。高荷电态电极还原峰电位低与电极的导电性高有关,低荷电态下和高倍率放电后电极的充电接受能力高与硫酸铅周围铅离子浓度高有关。硫酸铅晶体的尺寸随放电倍率增大逐渐变小,但不呈线性关系。The characteristics of lead sulfate for lead acid batteries during discharging processes and different discharge rates through the method of cyclic voltammetry(CV)and scanning electron microscope(SEM)technology.It is found that the conductivity of plate dominate the reduction action peak of PbSO4/Pb at the high state of charge,while the concentration of lead ions around PbSO4crystals promote the charge acceptance ability at low state of charge.It is also found that the relationship between discharge rate and PbSO4dimension can not keep in a linear relation.
