摘　　要：对空间镉镍电池的贮存时间、贮存条件进行了分析与对比,卫星在轨与地面试验数据表明在适合的贮存条件下,镉镍蓄电池组贮存时间小于3年,其电性能基本不受影响,可完成既定的飞行任务;经测试,贮存3.5年与贮存2年的镉镍电池相比,电池初始容量及其他参数基本相同,随着循环次数的增加,贮存时间较长的电池容量衰减较快;同批次电池在不同的条件下贮存后,其电性能表现不同,试验表明,镉镍电池适宜在-10～10℃下短路态贮存或完全放电态贮存.The storage periods and conditions of nickel-cadmium （Ni-Cd） batteries used in aerospace were investigated.The flight and ground experiment data show that the electrochemical properties of batteries doesn＇t have obvious deterioration in proper storage condition.The storage periods is within 3 years and the fixed flying task can be finishied.After tests,the batteries of 3.5 and 2 years storage periods are similar in initial capacity and other electrochemical parameters.The capacity of batteries stored for longer period degrades more rapidly with the increase of cycle time.The electrochemical properties of batteries in the same batch are different with the change of storage conditions.The test results show that the preferred storage condition for Ni-Cd batteries is short-circuit or fully discharged status at-10-10 ℃.
