Objective was to increase the reversible cycling capacity of anhydrous {alpha}-MnO{sub 2} by stabilizing its structure. We have synthesized various {alpha}-MnO{sub 2} materials and modified their structures via lithia doping in order to determine what properties are important for controlling cycling performance. A set of new stabilized {alpha}-[xLi{sub 2}O]{center_dot}MnO{sub 2} (x<0.2) cathode materials was synthesized, structurally characterized, and electrochemically evaluated.
