ABSTRACT:
Disclosed is a reversible, electrochemical cell having a high electrochemical activity, hydrogen storage negative electrode. The negative electrode is formed of a reversible, multicomponent, multiphase, electrochemical hydrogen storage alloy. The hydrogen storage alloy is capable of electrochemically charging and discharging hydrogen in alkaline aqueous media. In one preferred exemplification the hydrogen storage alloy is a member of the family of hydrogen storage alloys, derived from the V-Ti-Zr-Ni and V-Ti-Zr-Ni-Cr alloys in which the V, Ti, Zr, Ni and Cr are partially replaced by one or more modifiers, and the alloy has the composition:
