摘要：

Nonstoichiometric Zr-Mn-Ni-based Laves phase alloys were prepared and their electrochemical cycle life was examined in order to develop suitable alloys for the nickel-metal hydride battery. Both the stoichiometry and chemical composition of alloys were found to influence the electrochemical cyclic stability of alloys by changing their mechanical stability. In most cases the alloys with better mechanical stability exhibited longer cycle life, except the alloy with a high vanadium content. Also, the electrochemical cyclic stability of alloys was found to be closely related to their hysteresis factors in this alloy system. (C) 2002 The Electrochemical Society.
