Abstract

Abstract:

In order to improve the cycle stability of Ni/MH battery, the V₂Ti_0.5Cr_0.5Ni_1-_xMo_x(x=0.02-0.08) electrode alloys were prepared by arc-melting, and the effects of Mo content on microstructure and electrochemical properties were investigated systematically. The results show that all of the electrode materials mainly consist of a V-based solid solution phase with BCC structure and TiNi-based secondary phase which precipitates along the grain boundary of the BCC main phase. The electrochemical measurements indicate that the maximum discharge capacity of the alloy electrode increases firstly and then decreases with increasing x from 0.02 to 0.08. The cycle stability and electrochemical kinetic response of the alloy electrodes are strengthened firstly and then weakened, and reach the best performance at x=0.04.
