Summary:PROBLEM TO BE SOLVED: To provide a positive electrode for a lithium ion battery which has high durability and improved capacity density per unit volume.SOLUTION: A positive electrode for a lithium ion battery includes a positive electrode material which is formed by mixing a solid solution which comprises Li[LiMn]Oand LiM1O, (where M1 is at least one transition metals), and has total metal valence of 4, with a secondary active material represented by LiM2O, (where M2 is at least one transition metals having a total valence of 3), as a positive electrode active material.
