The disclosure relates to a silver oxide primary cell which includes a casing composed of a positive electrode container and a negative electrode container to define a sealed chamber between them, a positive electrode, an insulating layer, a negative electrode, a separator member, an electrically conductive member, and an insulating gasket housed in the sealed chamber. The electrically conductive member is pressed, at its portion protruding toward peripheral edge portion of the positive electrode, against the bottom face of the positive electrode container by the insulating gasket, and is simultaneously electrically connected to the bottom face or side wall of the positive electrode container.

Silver oxide primary cell

The present invention relates to a divalent silver oxide for use in primary cells which is stable in an alkaline solution, slow in the speed of oxygen gas generation with favorable reproducibility and has X-ray diffraction peak values different from that of conventional divalent silver oxide and the method of manufacturing the divalent silver oxide of the above described type. By the employment of the divalent silver oxide according to the present invention, it is possible to produce, at low cost, batteries having high energy density per unit weight and volume, with small amount of gas generation to prevent swelling or expansion of the cells.

Divalent silver oxide for use in primary cell and manufacturing method

A coulomb memory element having an electric current breaking action at a high allowable maximum voltage in which an electrolyte consisting mainly of a lead salt or a mixture of lead salts is charged between one or more inactive electrodes consisting of tungsten or tungsten plated with gold and one or more active electrodes consisting of pure lead which may be dissolved or deposited according to Faraday's law.
