摘要：

Hydrogen absorption-desorption properties, microstructures and electrode properties of V-based solid solution alloys (V3TiNi0.56Hfx, x = 0.046 and 0.24) were reported. In these alloys a Laves phase was precipitated, forming a three-dimensional network along grain boundaries of a V-based solid solution main phase. Cracking was observed to occur in and around the Laves phase after several charge-discharge cycles. The increase in fresh surface area was very useful in enhancing the high-rate capability of the electrode.
