摘　　要：考察了六次甲基四胺(HT)、十二烷基苯磺酸钠(SDBS)、十六烷基三甲基溴化铵(CTAB)、亚硫酸钠(Na2SO3)作为负极添加剂对密封AA型锌镍电池充放电、循环和自放电性能的影响,以及电解液用量对电池循环性能的影响。锌负极中同时加入SDBS、CTAB、Na2SO3的电池,第50次循环(1.0C恒流充放电)的放电容量为设计容量(400 mAh)的87.8%,常温存放28 d后和50℃下存放7 d后的放电容量分别为331.00 mAh和309.10 mAh,是设计容量的82.8%和77.3%。对于设计容量为400 mAh的电池,电解液的较佳用量为2.5 g。The effects of anode additives such as hexamethylene tetramine（HT）,sodium dodecyl benzene sulfonate（SDBS）,cetyl-trimethyl ammonium bromide（CTAB） and sodium sulfite（Na2SO3） on the performance of charge-discharge,cycle and selfdischarge of sealed AA type Ni-Zn battery,and the effects of electrolyte amount on the cycle performance of the battery were investigated.The discharge capacity of the battery adding SDBS,CTAB,Na2SO3 simultaneously was 87.8% of the designed capacity（400 mAh）at the 50th cycle（galvanostatic charge-discharge at 1.0 C）.The discharge capacities of the same after stored at normal temperature for 28 d and 50 ℃ for 7 d were 331.00 mAh and 309.10 mAh,respectively,which represented 82.8% and 77.3% of the designed capacity.The preferable electrolyte amount was 2.5 g to the Ni-Zn battery with a designed capacity of 400 mAh.
