Optimal Design Method of Small Lithium Primary Battery Structure by Eliminating Temperature Factor

针对军用微小型锂原电池激光焊接密封方式造成锂原电池电性能下降的问题,提出消除温度因素的锂原电池结构优化设计方法。该优化方法通过常温下机械密封收口加涂胶的方式替代高温焊接,消除温度因素对于电解液的影响,利用“迷宫”式密封通道来保证电池密封性,实现了微小型锂原电池结构优化。测试结果表明,消除温度因素的微小型锂原电池在高过载、高旋转、宽温域条件下的电性能输出稳定,满足苛刻环境下使用要求。

In view of the problem that the electrical performance of the lithium primary battery decreases due to the laser welding method of the military small lithium primary battery,this paper proposed an optimal design method for the structure of the lithium primary battery that eliminates the temperature factor.This optimization method replaced high-temperature welding with mechanical sealing and glue coating at room temperature,eliminated the influence of temperature factors on the electrolyte,used“labyrinth”sealed channels to ensure battery sealing,and realized the structural optimization of small lithium primary batteries.The experimental test results showed that the small lithium primary battery eliminating the temperature factor had stable electrical output performance under high overload,high rotation,and wide temperature range conditions,and met the using requirements in harsh environments.
