摘要：

The structure and electrochemical properties of Ti0.25V0.35Cr0.40-xNix (x=0.05-0.40) solid solution alloys have been studied in the paper. It is found that these alloys consist of a main solid solution phase with body centered cubic (bcc) structure and a little TiNi-based secondary phase. The solid solution alloys show easier activation behavior at 313 K as a negative electrode material for MH-Ni battery. With changing x from 0.05 to 0.30, the discharge capacity and the high-rate dischargeability increase. The discharge capacity increases with increasing temperature. The maximum discharge capacity is 240 mA h/g at 313 K for x = 0.30 and 280 mA h/g at 343 K for x = 0.15. (C) 2004 International Association for Hydrogen Energy. Published by Elsevier Ltd.
