POSITIVE ELECTRODE MATERIAL FOR LITHIUM ION SECONDARY BATTERY AND MANUFACTURING METHOD OF THE MATERIAL |
| 摘要 |
PROBLEM TO BE SOLVED: To provide a new positive electrode material for a lithium ion battery having excellent battery characteristics. SOLUTION: The positive electrode material for lithium ion battery consists of a lithium-containing composite oxide expressed by LiMn1-yFeyO2, (0<y<0.5) substantially formed from a rhombic phase, and is manufactured through such processes that lithium compound, oxidizing agent, and alkali are added to and mixed with a solution containing manganese ions (II) and iron ions (III) and then the obtained mixture solution is subjected to a hydrothermal treatment at a temperature of 400 deg.C or below. |
