Abstract
The present invention is directed to a metal/hydrogen alkaline storage battery, which comprises a positive electrode of a metal oxide, a negative electrode of a hydrogen-storage alloy, and a separator impregnated with an alkaline electrolyte and placed between the positive and negative electrodes. The electrodes and separator are housed within a sealed type battery casing. The casing has a device for maintaining the pressure in the battery in a selected range of from an equilibrium pressure required for absorbing hydrogen by the negative electrode to about 20 kg/cm.sup.2.
