Abstract
A cell which employs an active metal anode such as lithium and a liquid organic electrolyte that is improved by the use of a cathode comprised of carbon fluoride chloride is described. The cathode comprises a carbon fluoride chloride of the general formula (C.sub.y F.sub.x Cl.sub.z).sub.n wherein y is 1 to 2, x is greater than 0 to 1.2, z is .ltoreq.0.1 and n defines the number of repeating units occurring in the carbon fluoride chloride molecule of high molecular weight. The resulting battery has improved discharge and shelf-life characteristics.
