Abstract:
1. A method of making a primary lithium battery comprising a cathode including cathode active material, comprising (a) blending a lithiated manganese dioxide and a carbon fluoride to provide a cathode mixture including the lithiated manganese dioxide and the carbon fluoride in a specific weight ratio; (b) using the cathode mixture to form a cathode adjacent a first surface of a separator, wherein the only cathode active material in the cathode consists of the lithiated manganese dioxide and the carbon fluoride in the specific weight ratio; (c) providing an anode adjacent to a second surface of the separator; (d) assembling the cathode, separator, and anode into a cylindrical housing to provide the primary lithium battery, and wherein the lithiated manganese dioxide has a specific surface area of between 10.0 m
