摘　　要：通过对添加不同电解液量MH/Ni电池的密封性、放电容量、电压平台和循环寿命的检测 ,研究了电解液量对电池电化学性能的影响。结果表明 ,对于AA型MH/Ni电池 ,当添加的电解液量 >3 0g或 <2 6g时 ,会导致电池内阻增大和放电容量、放电电压平台的降低 ,同时电解液过多会导致电池漏液。较为合适的电解液量是 2 7～ 2 9g,这时电池内压较低 ,循环寿命较高 。The electrochemical properties of MH/Ni batteries which were added with different amount of electrolyte were investigated.The experiments results demonstrated that the internal resistance increased as well as the discharge capacity,discharge voltage plateau decreased when the amount of electrolyte was more than 3.0g or less than 2.6g.The batteries which contained 2.7～2.9g electrolyte showed lower internal pressure and higher cycle life.In addition the discharge capacity and discharge voltage were highest.
