    • PURPOSE:To minimize the voltage reduction of a nonaqueous solvent battery during its initial stage of large current electric discharge and shorten the time for voltage recovery by adding a vinyl chloride-vinylidene chloride copolymer to prepare the liquid electrolyte. CONSTITUTION:A can 1 contains a liquid electrolyte 13 poured through a pipe- like positive terminal 10. The liquid electrolyte 13 is prepared by adding 2.5g/l of vinyl chloride-vinylidene chloride copolymer to a solution prepared by dissolving 1.5mol/l of aluminum chloride and 1.5mol/l of lithium chloride in thionyl chloride. After a stainless steel needle 14 is inserted in the positive terminal 10, the needle 14 and the end of the terminal 10 are fused by laser welding to seal the terminal 10. Owing to the above structure, only a slight voltage decrease occurs during the initial stage of large current electric discharge. Furthermore, it is possible to reduce the time for voltage recovery.
    • 目的:为了最大限度地减少非水溶剂电池在大电流放电初期的电压下降,并通过加入氯乙烯 - 偏二氯乙烯共聚物来缩短电压恢复时间以制备液体电解质。 构成:罐1包含通过管状正极端子10注入的液体电解质13.液体电解质13通过将2.5g / l氯乙烯 - 偏二氯乙烯共聚物加入到通过将1.5mol / l的 氯化铝和1.5mol / l氯化锂在亚硫酰氯中的溶液。 在正极端子10中插入不锈钢针14后,针14和端子10的端部通过激光焊接熔接以密封端子10.由于上述结构,在初始时仅发生轻微的电压降低 大电流放电阶段。 此外,可以减少电压恢复的时间。
