Abstract

851,201. Batteries. UNION CARBIDE CORPORATION. Oct. 9, 1958 [Oct. 9, 1957], No. 32201/58. Drawings to Specification. Class 53 A cathode for a primary or secondary dry cell consists of a mixture of a depolarizing oxide and carbon particles bound together with Portland cement or a cement consisting of a mixture of magnesium oxide and magnesium chloride. The depolarizer may consist of an oxide of manganese, mercury, silver, copper, nickel or vanadium, and the carbon may be carbon black, acetylene black or graphite. Steel wool may be included in the mixture. The whole is moistened with a solution of potassium hydroxide and moulded into shape by pressure, or introduced into the cell container by extrusion. In an example, a mixture of manganese dioxide, graphite, Portland cement and potassium hydroxide solution is pressed into a cake which is allowed to set and is then pulverized and sieved. The powder is again moistened with potassium hydroxide solution and moulded into the required shape. Small quantities of graphite and cement are added during the moulding process.
