Abstract
A rechargeable battery has a pair of electrodes, one having nickel hydrox as the active component and the other comprising as active component an amorphous alloy of at least one element selected from the group consisting of early transition metals and rare earth metals; and at least one late transition metal; the battery displays superior characteristics as compared with conventional Ni-Cd rechargeable batteries; essentially the battery functions as a hydrogen cell, involving intercalation of hydrogen into the amorphous alloy; a new method of charging involves charging a rechargeable cell and periodically interrupting the charging for a short interval and electrically shorting the cell during the short interval.
