多片并联层叠电堆的锂/二氧化锰储备电池

Lithium/Manganese Dioxide Reserve Battery with Multichip Parallel Stacked Pile

针对传统锂/二氧化锰电池不能满足引信使用条件的问题,提出多片并联层叠电堆的锂/二氧化锰储备电池。多片并联结构通过引线连续折绕于电极极耳实现,电极叠堆采用单条隔膜在正负电极间往复平行折叠,达到电堆的可靠集流与绝缘。实验验证结果表明,储备电池样机超过600 mA/5 V(3 W)可连续放电121 s,马歇特23齿锤击激活时间为39 ms/3 V,且在工作状态下可以承受马歇特锤击的过载冲击。

Aiming at the problem that the traditional lithium/manganese dioxide battery can not meet the working conditions of fuze,a lithium/manganese dioxide reserve battery with multichip parallel stacked pile was proposed.The multichip parallel structure was achieved by the continuous periphrasis of leads through the electrode pole ears,together with the electrode stacking accomplished by the reciprocating parallel folding of single diaphragm between positive electrodes and negative electrodes,resulting in reliable current collection and insulation of the pile.The verification test showed that the reserve battery prototype maintained discharging for 121 s in excess of 600 mA/5 V,with the activation time of 39 ms/3 V by Machete 23 tooth hammering,meanwhile,the prototype was able to bear the overload shock of Machete hammering in working condition.
