PREPARATION OF: I. INTERCALATIVE METAL OXIDE/CONDUCTIVE POLYMER COMPOSITES AS ELECTRODE MATERIALS FOR RECHARGEABLE BATTERS; II. SODIUM RICH MANGANESE OXIDE HYDRATE WITH CAPACITY FOR AQUEOUS Na-ion ELECTROCHEMICAL ENERGY STORAGE

摘要

The present invention is directed at intercalative metal oxide/conductive polymer composites suitable for use as electrode materials for rechargeable batteries. The composites can be prepared by agitation of the metal oxide and the conductive polymer in aqueous media. The present invention is also directed at a sodium rich layered manganese oxide hydrate prepared by annealing manganese (II, III) oxide and sodium hydroxide. The sodium rich manganese (III, IV) oxide so formed indicates an enhanced capacity for Na-ion storage suitable for the use of electrode materials for aqueous energy storage.
