METHODS OF MAKING LITHIUM METAL COMPOUNDS USEFUL AS CATHODE ACTIVE MATERIALS

摘要

The invention provides a novel method for making lithium mixed metal materia ls in electrochemical cells. The lithium mixed metal materials comrise lithium and aat least one other metal besides lithium. The invnetion involves the reaction of a metal compound, a phosphate compound, with a reducing agent to reduce the mettal and form a metal phosphate. The invention also includes methods of making lithium metal oxides involving reaction of a lithium compound, a metal oxide with a reducing agent.
