METHOD OF MAKING LAMBDA-MANGANESE DIOXIDE

摘要

A method of making a primary alkaline battery that includes a cathode includingλ-MnO2 as an active material, an anode including zinc or zinc alloy as an active material, a separator between the cathode and anode, and an alkaline electrolyte contacting the anode and cathode having improved discharge performance. Methods of making high-purity, essentially lithium-freeλ-MnO2 having high electrochemical activity from nominally stoichiometric lithium manganese oxide spinels are disclosed.
