POSITIVE ELECTRODE ACTIVE MATERIAL, LITHIUM BATTERY, AND PROCESS OF MANUFACTURING POSITIVE ELECTRODE ACTIVE MATERIAL |
| 摘要 |
PROBLEM TO BE SOLVED: To provide a positive electrode active material exerting excellent discharge capacity.SOLUTION: The positive electrode active material includes a crystal phase of an inverse spinel structure represented by LiMFeVO(M is Co or Ni, and x satisfies 0<x<1, further preferably, satisfies 0<x≤0.3). The lithium battery includes a positive electrode layer containing the positive electrode active material, a negative electrode layer containing a negative electrode active material, and an electrolyte layer. The process of manufacturing the positive electrode active material includes: an adjustment step that adjusts a raw material solution; and a heat treatment step that removes a solvent and performs a heat treatment. |
