摘要
A high charge retention, reversible, multicomponent, multiphase, electrochemical hydrogen storage alloy comprising titanium, vanadium, zirconium, nickel, and chromium. The hydrogen storage alloy is capable of electrochemically charging and discharging hydrogen in alkaline aqueous media. In one preferred exemplification the hydrogen storage alloy comprises (Ti2-xZrxV4-yNiy)1-zCrz where 0.0 is less than x is less than 1.5, 0.6 is less than y is less than 3.5, and z is an effective amount less than 0.20. Also disclosed is a rechargeable, electrochemical cell (10) utilizing a negative electrode (12) formed of the alloy.
