摘　　要：在锌负极活性物质中添加ZnSO4,用恒流充放电法研究了ZnSO4添加量对Zn-Ni电池性能的影响。添加适量ZnSO4可减少电池的内阻和内阻增大速度、提高负极活性物质利用率、延长电池循环寿命;添加1.0%对提高负极材料利用率的效果最明显;添加2.0%对减少电池内阻和延长电池循环寿命最有效;但ZnSO4的添加量不宜过大。ZnSO4 was added in Zn anodes. The effects of adding amounts of ZnSO4 on the performance of Zn-Ni battery were tested by galvanostatic charge/discharge tests. The internal resistance and internal resistance increasing speed could be decreased, the active material utilization of anodes,and the cycle life of battery of zinc anodes could be improved by adding proper amount of ZnS04. Adding 1.0% ZnSO4 could best improve the anode material utilization. Adding 2.0% ZnSO4 could most effectively improve the internal resistance and cycle life but ZnSO4 was not suit to be added too much.
