description A flat, long-life alkaline primary cell having a low water content comprises a positive electrode of mercuric oxide or silver oxide, a negative electrode of amalgamated zinc or cadmium, and separator layers disposed between the electrodes. The positive electrode lies upon a disc of nickel screening. Flanged edges of two of the separator layers are gripped between a cover and a sealing ring. The electrolyte absorbed by the separator layers is a mixture of sodium hydroxide, potassium hydroxide, and rubidium hydroxide. The number of moles of water per mole of alkali hydroxide is 2.0-2.7 for sodium hydroxide, 2.4-3.1 for potassium hydroxide, and 2.8-4.0 for rubidium hydroxide.
