金属氢化物镍电池的自放电因素分析

摘要

金属氢化物镍电池的自放电与多种因素有关。论述了正极中的钴含量、电解液的组成、氢气等对正极活性物质自分解的影响。同时还讨论了隔膜材料、负极贮氢材料中的锰含量以及化成方法对氢化物镍电池自放电的影响。%The self - discharge of nickel - metal hydride battery was related to various factors. The influcences of cobalt contents in nickel hydroxide electrode, electrolyte compositions and hydrogen gas on the self - decomposition of positive active material were discussed. The effects of the separator materials,manganese contents in anode alloy and the formation process on the self-discharge of nickel metal hydride battery were also discussed.
