CATHODE MATERIAL FOR LITHIUM BATTERY AND METHOD OF PRODUCTION THEREOF

摘要

A cathode composition for lithium ion and lithium metal batteries includes a transitional metal oxide and an adsorbate layer disposed on a surface of the transitional metal oxide. The transitional metal oxide and the adsorbate layer are both electrochemically active. A method of forming cathode materials for lithium ion and lithium metal batteries includes the steps of providing reagents including at least one elemental chalcogenide or chalcogenic oxide and a transitional metal oxide. The reagents are heated, wherein a cathode composition is formed having a chalcogenic complex adsorbed to a bulk material, the bulk material being a modification of the transitional metal oxide. The transitional metal oxide is preferably a vanadium oxide.
