Abstract

579,849. Batteries. MALLORY & CO., Inc., P. R. Sept. 13, 1943, No. 15028. Convention date, Aug. 26, 1942. [Class 53] A primary cell, for use in low temperatures, comprises a zinc or cadmium electrode, a depolarizing electrode comprising a metal sheet with a conducting depolarizing composition such as copper oxide adhering to it, a semipermeable membrane such as " Cellophane " (Registered Trade Mark) separating the two electrodes, and an alkaline electrolyte, such as the hydrate of potassium, sodium, or lithium. The membrane may be spaced from one or both electrodes (a) by an intermediate fibrous layer of nylon, glass fabric &c. or (b) by corrugating or embossing one of the electrodes. Fig. 1 shows a cell comprising coiled sheet materials including a zinc foil electrode 12, two layers 17, 18 of nylon, two layers 15, 16 of regenerated cellulose, and a steel electrode 14 coated with cupric oxide, graphite, and a binder, such as a solution of polymerized vinyl chloride. The coated steel strip is rolled under pressure at a temperature of 125‹C. An additional coating of pure graphite and binder may be sprayed on to the cupric oxide-graphite layer. In place of cupric oxide, sulphides of copper or lead, or lead oxides may be used. The electrolyte is absorbed by the layers 15, 16, 17, 18. In Fig. 4, cellulose sheets 15, 16 engage each side of the zinc foil 12, and the coated steel electrode 28 is corrugated. The coiled electrodes &c. held in rolled form by a rubber band may be supported in a steel can 21, Fig. 2, filled with electrolyte, and provided with a shoulder on which rests a closing disc 23 through which projects the threaded portion of a zinc rod 11 connected to the zinc foil 12. The rim of the can is spun over a rubber ring 24 to seal the can. In a modification, Fig. 3 (not shown), a disc of dry potassium hydrate is placed at the bottom of the can, and the cell activated when required by adding water. The electrolyte preferably contains at least 33 per cent. of potassium hydrate. The strips of fibre may be impregnated with electrolyte before coiling, the use of a cloth spacer or a corrugated electrode being then unnecessary.
