The electrode characteristics of two kinds of metal hydride electrodes using V-Ti (V-rich) based alloy were studied, in which one electrode was prepared by sintering the mixture of V-Ti alloy and Ni powders by a rapid thermal annealing technique and the other one was prepared using V-Ti-Ni ternary alloy, The discharge capacities of all electrodes during the charge-discharge cycling were completely deteriorated within 10 cycles. It appeared that the deterioration of the electrodes was caused by the dissolution of V in the near-surface region into the electrolyte and the formation of $TiO_2$ layer on the alloy particle surface. This degradation mechanism was supported by the facts that V is main hydride forming element and $TiO_2$ has very low electrical conductivity and hydrogen diffusivity.
