Optimal Design Method of Small Lithium Primary Battery Structure by Eliminating Temperature Factor
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,elimi-nated 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 per-formance under high overload,high rotation,and wide temperature range conditions,and met the using require-ments in harsh environments.
