摘要
针对某技术试验卫星首发星,研制过程中投产的锌-氧化银电池(以下简称锌银电池)干态贮存时间超出规范规定(干态贮存时间小于5年)的现状,为验证该批次电池在超期贮存条件下仍能满足卫星飞行任务的需要,本文从锌银电池失效模式分析出发,对干态贮存电池隔膜力学特性、隔膜上的银含量对电池性能的影响开展分析,同时开展同批次锌银电池干态超期贮存可靠性延寿试验。试验结果表明,该批次电池的隔膜力学特性、隔膜氧化程度、锌银电池一次活化后等性能指标均可以满足卫星的任务需求。卫星成功完成任务,经过在轨安全无异常运行,证明了分析和试验验证的有效性。
For the first-launched satellite of a technology experimental satellite,the dry state storage time of zinc-silver oxide batteries(hereinafter referred to as the zinc-silver batteries)put into production during the development process exceeds the dry storage time of less than 5 years stipulated in the criterion.In order to analyze the influence of extended storage on the performance of this batch of batteries,this paper,based on the FMEA of zinc-silver batteries,analyzed the influence of dry storage of zinc-silver batteries on the positive and negative electrodes,the change of separator mechanical characteristics,and the influence of silver content change in separator effect on the performance of the battery.Meanwhile,the reliability extension test of dry storage of the same batch of zinc-silver batteries was carried out to analyze the influence of dry storage of zinc-silver batteries on the performance.The separator mechanical characteristics,the oxide of separator,and the first activation result of zinc-silver battery approve that this series of batteries can satisfy the mission requirements of the satellite.The successful satellite mission approves of the analysis method and the reliability extension test are helpful.
