Abstract:
A positive electrode active material is formed of a lithium containing layered oxide. The lithium containing layered oxide contains either or both of LiANaBMnxCoyO2±α that belongs to a space group P63mc or LiANaBMnxCoyO2±α that belongs to a space group Cmca. The lithium containing layered oxide contains the LiANaBMnxCoyO2±α as a solid solution, a mixture or both of them. In the LiANaBMnxCoyO2±α, 0.5≦A≦1.2, 0
