Abstract
A method for the preparation of a highly alloyed metal hydride, hydrogen storage alloy material including titanium, zirconium, vanadium, nickel and chromium. The hydrogen storage alloy material is prepared by vacuum induction melting electrochemically operative amounts of the materials in a nigh density, high purity graphite crucible, under an inert gas atmosphere.
