Modified electrochemical hydrogen storage alloy having increased capacity, rate capability and catalytic activity

摘要

A modified Ti-V-Zr-Ni-Mn-Cr electrochemical hydrogen storage alloy which has at least one of the following characteristics: 1) an increased charge/discharge rate capability over that the base Ti-V-Zr-Ni-Mn-Cr electrochemical hydrogen storage alloy; 2) a formation cycling requirement which is reduced to one tenth that of the base Ti-V-Zr-Ni-Mn-Cr electrochemical hydrogen storage alloy; or 3) an oxide surface layer having a higher electrochemical hydrogen storage catalytic activity than the base Ti-V-Zr-Ni-Mn-Cr electrochemical hydrogen storage alloy.
