POSITIVE ELECTRODE FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY, METHOD FOR PRODUCING THE SAME, AND NONAQUEOUS ELECTROLYTE SECONDARY BATTERY

摘要

[Object] To provide a positive electrode for a nonaqueous electrolyte secondary battery with which characteristics of the nonaqueous electrolyte secondary battery, such as a charge/discharge efficiency, a capacity retention ratio, and a discharge capacity retention ratio are not easily degraded even in the case where the nonaqueous electrolyte secondary battery is continuously charged at a high temperature.;[Solution] A positive electrode 12 of a nonaqueous electrolyte secondary battery 1 includes a positive electrode active material layer 12b. The positive electrode active material layer 12b contains a positive electrode active material and a compound represented by a general formula (1): MH2PO2 (1). In the general formula (1), M represents a monovalent cation.
