POSITIVE ELECTRODE ACTIVE MATERIAL FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY AND MANUFACTURE THEREOF |
| 摘要 |
PROBLEM TO BE SOLVED: To improve the thermal stability of a battery without hindering the initial capacity of the battery while maintaining the excellent cycle characteristic. SOLUTION: This positive electrode active material is composed of the hexagonal crystal lithium containing compound oxide expressed with a chemical formula LiNi1-x-yCoxTiyO2 (0<x<=0.20, 0<y<=0.07) and having the layered structure. In the case of displaying each site of 3a, 3b, 6c of the lithium containing compound oxide with [Li]3a[Ni1-x-yCoxTiy]3b[O2]6c, site occupation factor of the metal ion except for lithium in the 3a site obtained by the Rietveld analysis by the X-ray diffraction of the lithium containing compound oxide is set at 5% or less. |
