METHOD FOR PREPARING LITHIUM METAL COMPOUND USEFUL AS CATHODE ACTIVE MATERIAL |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a novel method for preparing a lithium-mixed metal material for use in an electrochemical cell. <P>SOLUTION: The lithium-mixed metal material comprises lithium and at least one metal other than lithium. The method comprises a step of reacting a metal compound and a phosphate compound with a reducing agent for reducing the metal and forming a metal phosphate. A method for preparing a lithium metal oxide comprising a step of reacting a lithium compound and a metal oxide with a reducing agent is also provided. <P>COPYRIGHT: (C)2009,JPO&INPIT |
