POSITIVE ELECTRODE MATERIAL FOR LITHIUM ION SECONDARY BATTERIES, AND METHOD FOR PRODUCING SAME |
| 摘要 |
The present invention relates to a lithium manganese composite oxide having a metal-containing compound film and a carbon coating, in which at least a part of a surface of the lithium manganese composite oxide represented by Formula (1) is coated with the metal-containing compound film, and at least a part of the surface thereof is further coated with the carbon coating. The present invention can provide a positive electrode material capable of improving the discharge characteristics and the capacity retention rate after cycles of lithium ion secondary batteries.;Li1+x(FeyNizMn1-y-z)1-xO2 (1),where 0<x<⅓, 0≦y, 0≦z<0.5, and y+z<1. |
