Abstract

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.
