Abstract
A method for making the anode (or the cathode) of a nickel-metal hydride battery by electrodepositing a metal in the interstitial spaces a bed of metal-hydride active material particles (or electrodepositing a metal in the interstitial spaces of a bed of nickel hydroxide particles). Alternatively, the anode (or cathode) can be made by pressing metal-hydride active material particles (or nickel hydroxide particles) into a cellular metal substrate formed by electrodepositing a metal in the interstitial spaces of a bed of particles. Or, the anode (or cathode) can be made by flowing a suspension of metal-hydride active material particles (or nickel hydroxide particles) through a cellular metal substrate formed by electrodepositing a metal in the interstitial spaces of a bed of particles.
