Nickel-metal hydride batteries and electrodes capable of increased power output and recharge rates. 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. The electrode tab are directly attached to the porous metal substrate via a low electrical-resistance connection which includes welding, brazing, or soldering.
