摘　　要：研究了集流方式(二极耳、三极耳、集流盘)对AA 1 300 mAh高功率Ni-MH电池性能的影响,通过充放电、倍率性能、内压特性、循环性能和过充性能等电化学性能的测试优化工艺标准。测试结果表明:三种集流方式都能提高Ni-MH电池的大电流放电容量和放电电压平台,其中集流盘效果最好,三极耳次之,二极耳最差。The effects of different current collecting ways（two tabs,three tabs,collecting） on the performance of AA 1 300 mAh high-power MH-Ni batteries were studied.The process standards were optimized through the electrochemical performance tests,including charge-discharge test,rate teat,internal voltage test,cycling test and over-discharge test.The test results show that all the three current collecting methods can improve the large current discharge capacity and the discharge platform.Among three current collecting methods,collector is the best,followed by three tabs,and two tabs is the worst.
