Non-aqueous electrolyte secondary battery positive electrode, a manufacturing method thereof, and a nonaqueous electrolyte secondary battery

A even when the nonaqueous electrolyte secondary battery was continuously charged at a high temperature, non-aqueous charge-discharge efficiency of electrolyte secondary battery, the capacity retention rate, characteristics such as the discharge capacity retention ratio hardly deteriorated, non-aqueous to provide a positive electrode for electrolyte secondary battery. A nonaqueous cathode 12 of the electrolyte secondary battery 1 includes a positive electrode active material layer 12b. The positive electrode active material layer 12b includes a positive electrode active material, the general formula In general formula (1), M is a monovalent cation. .FIELD 1
