Abstract
Nickel-metal hydride batteries and electrodes are capable of increased power output and recharge rates. The electrodes and batteries produced therefrom exhibit increased internal conductance. The positive and negative electrodes may be formed by pressing powdered metal-hydride active materials into porous metal substrates. The porous metal substrates are formed from copper, copper-plated nickel, or a copper-nickel alloy, and may be additionally plated with a material which is electrically conductive and resistant to corrosion in the battery environment, such as nickel.
