ABSTRACT:
A novel high energy density aqueous cell exhibiting superior electrochemical properties is described. The use of the novel cathode composition, (C.sub.y F.sub.x Cl.sub.z).sub.n, permits the construction of a novel high energy density aqueous cell comprised of an anode, an alkaline electrolyte and a cathode, said cathode comprised of carbon fluoride chloride of the type (C.sub.y F.sub.x Cl.sub.z).sub.n : wherein y is 1 or 2; x is greater than 0 up to about 1.2; z is greater than 0 up to 0.1; and n denotes an infinitely large two dimensional array of C.sub.y F.sub.x Cl.sub.z units.
The carbon fluoride chloride is composed of carbon, fluorine and chlorine, wherein the carbon can be chosen from the group consisting of graphite, coke, needle coke, charcoal, activated carbon, carbon blacks and the like. The carbon fluoride chloride described herein can be made in several ways, e.g. carbon can be reacted with chlorine monofluoride, ClF, to produce (C.sub.y F.sub.x Cl.sub.z).sub.n or with mixtures of chlorine, Cl.sub.2, and fluorine, F.sub.2, to produce (C.sub.y F.sub.x Cl.sub.z).sub.n.
