采用化学法和熔炼法对废镍氢电池中的储氢合金进行再生。化学处理再生的合金具有相同的CaCu5结构，但电化学容量低于原合金。当废合金经过化学处理再用电弧熔炼熔炼时，其结构和电化学性能可以得到很好的恢复。结果发现，再生合金的放电性能和寿命均能达到原合金的水平。
The hydrogen storage alloy from spent Ni–MH batteries was regenerated by chemical and smelting method. The alloy regenerated by chemical treatment has the same CaCu5structure, but the electrochemical capacity is lower than that of the original alloy. When the spent alloy was chemically treated and then smelted by arc-melting, its structure and electrochemical properties could be well recovered. It is found that the discharge properties and lifetime of the regenerated alloy can reach the level of the original alloy.
