摘　　要：介绍了国内外废旧电池的回收概况以及火法和湿法回收金属氢化物 -镍电池的工艺流程。指出传统的火法或湿法回收工艺复杂 ,成本高 ,有价金属回收率低 ,且使用各种化学试剂又会对环境造成二次污染。提出在系统分析金属氢化物 -镍电池失效原因的基础上 。The general situation of recycling and reusing for nickel metal hydride batteries and its fire metallurgy and hydrometallurgy technical processes are summarized. The traditional recycling processes are not only complex in technology, higher at cost and lower with recovery of noble metals, but also pollute the environment because of chemical reagents used. Some simple and feasible approaches for battery recycling without destroying are put forward and discussed on the basis of degradation analysis of electrochemical performance for nickel metal hydride batteries.
