ABSTRACT:
A method of making a rechargeable battery electrode material containing manganese oxide is provided. The method includes preparing an aqueous solution of manganese nitrate and dissolving bismuth nitrate into the solution. The mixture is heated to evaporate the water contained in the mixture and is further heated to facilitate decomposition of the nitrates in the mixture to form a compound containing manganese oxide and bismuth oxide. The compound is maintained at a temperature of between about 200 to 300 degrees Celsius for an additional 12 hours. Thereafter, the compound is cooled and ground to a desired particle size for use as a rechargeable battery electrode material. The compound may alto be mixed with commercially prepared electrolytic or chemical manganese dioxide to obtain a highly rechargeable battery electrode material. A related battery cell is also disclosed.
