Abstract

The effects of composition modification on the electrochemical discharge properties were explored for the nonstoichiometric ZrMn_0.6V_0.2Ni_1.2M_0.05 (M= Fe, Ni, Cu, Al) C15 Laves phase alloy electrodes. Modification of ZrMn_0.6V_0.2Ni_1.2Co_0.1 by addition of a small amount of La was also made. The gas-phase hydrogenation pressurecomposition-temperature (P-C-T) curves were used to evaluate the possible electrochemical performance. Among them, the Al-added composition exhibited the best discharge performance and the least pulverization after the cyclic test. The better performance is explained based on the electrochemical characteristic and particle morphology.
