Abstract
In this paper, phase structure and electrochemical properties of the overstoichiometric hydrogen storage electrode alloys Zr 1− x Ti x (Mn 0.7V 0.2Co 0.1Ni 1.2) have been investigated. The results showed that when the Ti content increased, the content of the C15 Laves phase decreased while that of the C14 Laves phase increased. At same time, the high Ti content inhibited the appearance of secondary phase Zr 7M 10 in the alloys. When x = 0. 2, the storage hydrogen electrode alloy Zr 0.8Ti 0.2 (Mn 0.7V 0.2Co 0.1Ni 1.2) possessed the maximum discharge capacity 354 mAh/g, and preserved 91% of total capacity at current 300 mA/g. Due to a few La additation, the alloy Zr 0.75Ti 0.2La 0.05Mn 0.7V 0.2Co 0.1Ni 1.2 reached the maximum capacity 372 mAh/g after 4 cycles, compared to 14 cycles for the alloy without La, and preserved 93% of the maximum capacity after 30 cycles.
