钒是一种高容量吸氧金属，但它不能作Ni-H电池的活性物质使用。近来，根据一种全新的设计思路，即是把具有极高容量的贮氢相钒固港体作母相并在其品界上析出TiNi相或C14型Laves相（晶界相承担微观集电子的功能），开发成功了贮氢容量比传统合金高50％以上的高容量电池用合金． Vanadium is a high-capacity oxygen-absorbing metal, but it can not be used as an active material for Ni-H batteries. Recently, according to a completely new design concept, a vanadium-rich solid phase with a very high capacity for hydrogen storage is used as a mother phase and a TiNi phase or a C14-type Laves phase is precipitated on its boundary (the grain boundary phase assumes the micro-electron collector Function), the successful development of the hydrogen storage capacity of more than 50% higher than the traditional high-capacity alloy battery alloy.
