A method of making a rechargeable modified manganese dioxide material for use as battery electrode is disclosed. The method includes mixing manganese dioxide with an aqueous solution of a water soluble salt component selected from the group consisting of bismuth nitrate, lead acetate, lead nitrate, copper sulfate, copper nitrate, copper chloride and mixtures thereof. An alkaline hydroxide solution is then added to establish precipitation of resultant product. The resultant product is washed, filtered and dried to obtain the modified manganese dioxide material. The material is combined with a suitable conducting reinforcement component and a binder to form a high density, low resistivity electrode material.
