摘　　要：本文报告了一种方法评估储氢合金电极的循环寿命。使用储氢合金粉末微电极,适当地选择电位扫描范围和扫描速度,做循环伏安曲线,用氧化峰面积代表电极的放电量,可以测得放电量随时间的变化曲线,从而得到电极容量的衰减曲线。相对于常规寿命测试方法,本方法用时大大减少,且操作简便,结果准确。A method to test the cycle life of hydrogen storage alloy electrode was reported. The cyclic voltammograms were obtained by employing powder microelectrode and selecting properly the range of scan potential and scan rate. The area of oxidizing peak standing for discharge capacity of electrode,the relationship between capacity and cyclic number was reported. Comparing with conventional method this method had many advantages,such as short time for testing,easy operation and reliable results.
