Nickel-metal hydride batteries and electrodes capable of increased power output and recharge rates. The positive and negative electrodes (1) may be formed by pressing powdered metal hybride active materials into porous metal substrates. The porous metal substrates are formed from copper, copper-plated nickel, or a copper-nickel alloy. The electrode tabs (2) are directly attached to the porous metal substrate via a connection which includes welding, brazing, or soldering.
L'invention concerne des accumulateurs à hydrure métallique de nickel et des électrodes pouvant produire une énergie accrue et se recharger à des vitesses également accrues. On peut former les électrodes (1) positive et négative en comprimant des matières actives à base d'hydrure métallique en poudre, de façon à obtenir des substrats métalliques poreux. Ces substrats métalliques poreux sont constitués de cuivre, de nickel à plaquage de cuivre, ou d'un alliage cuivre-nickel. On fixe directement les fiches plates d'électrode (2), sur le substrat métallique poreux, au moyen d'une connexion électrique, par soudure, brasage fort ou brasage tendre.
