Abstract

659,368. Primary batteries. DOW CHEMICAL CO. Sept. 9, 1949, No. 23420. Convention date, Jan. 27. [Class 53] A primary cell has a carbon cathode surrounded by manganese dioxide, a magnesium or magnesium alloy anode, and an electrolyte consisting of an aqueous solution of ammonium bromide. The magnesium alloy may contain small quantities of aluminium, zinc, calcium, and manganese and to prevent corrosion of the anode by the electrolyte the latter may. contain chromates or bichromates of sodium, lithium, calcium, or ammonium. Fig. 1 shows one form of cell in which a receptacle 1 is divided by a perforated partition 4 on one side of which is a sheet 6 of porous material such as filter paper. The compartment 2 contains a magnesium plate 7 immersed in a solution of ammonium bromide, the compartment 3 containing a carbon rod 10 surrounded by a mixture of manganese dioxide and finely divided carbon moistened with the electrolyte. A dry cell is also described having a magnesium container, a central carbon rod surrounded by a manganese dioxide depolarizer, and a jelly electrolyte of ammonium bromide between the depolarizer and container.
