ABSTRACT:
A sealed storage battery for use in potable power supply is improved by using metal oxide-hydrogen storage alloy to have a higher capacity and a smaller weight. The battery has a structure which comprises a combination of a positive electrode having a high energy density in a wide range of temperature and consisting of a bulk high porosity body filled with an active material composed of solid solutions such as typical Co solid solution, oxide powders such as typically Ca(OH).sub.2 and ZnO, with an addition of graphite for rendering the electrode reaction effective; and a high capacity negative electrode of hydrogen storage alloy having a reduced equilibrium hydrogen pressure, and where the aforementioned characteristics at high temperatures are further enhanced by an electrolyte suitable to high temperatures, short-circuits are prevented by a chemically stable separator, and a structure sealing a container and a safety vent is excellent in air-tightness and reliability.
