Positive electrode active material, positive electrode and battery |
| abstract |
A positive electrode active material having a high capacity and excellent cycle characteristics and high-temperature storage characteristics is provided. A positive electrode active material is a composite particle comprising particles containing a lithium transition metal composite oxide containing Li and Co, and a layer containing an oxide containing Li, Ni and Mn provided on the surface of the particle. Ni and Mn have a concentration distribution from the surface of the composite particle toward the center. In the depth range where the ratio d (%) satisfies 0.04% ≦ d ≦ 0.20%, the molar fraction r n and the molar fraction r m are 0.05 ≦ r n and 0.05 ≦ r m , respectively. And the ratio r n2 / r n1 and the ratio r m2 / r m1 are in the range of 0.85 ≦ r n2 / r n1 ≦ 1.0 and 0.85 ≦ r m2 / r m1 ≦ 1.0, respectively. Is in. [Selection] Figure 1 |
