Ml(NiCuAlZn)_5合金制备及其电化学性能研究

PREPARATION AND ELECTROCHEMICAL PROPERTIES OF Ml(NiCuAlZn)_5 HYDROGEN STORAGE ALLOYS

利用中间合金法制备了无钴含锌混合稀土系储氢合金电极材料 Ml( Ni Cu Al Zn) 5 ,并对其晶体结构。

Ml(NiCuAlZn) 5 hydrogen storage alloys were prepared by intermediate alloy method. The crystal structure, thermodynamic and electrochemical properties were investigagted. The crystal structure of the Ml(NiCuAlZn) 5 is CaCu 5 type. The high rate dischargeability of Ml(NiCuAlZn) 5 electrode is better than that of the Ml(NiCuAl) 5 electrode. The replacement of Ml by a small amount of Mm is useful improving the equilibrium pressure of the Ml(NiCuAlZn) 5 hydrogen storage alloys.$$$$
