POSITIVE ELECTRODE FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY, ITS MANUFACTURING METHOD, AND NONAQUEOUS ELECTROLYTE SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a positive electrode for a nonaqueous electrolyte secondary battery that is excellent in binding strength between a positive electrode mix layer and a positive electrode collector and in cycle characteristics being important characteristics of a battery, and a nonaqueous electrolyte secondary battery including the same.

SOLUTION: The positive electrode for the secondary battery is composed by binding among primary particles 12 of a positive-electrode active material with a water-soluble polymer binder 13, and by binding among secondary particles 9 being aggregates formed of the connected primary particles 12 and between the secondary particles 9 and the positive electrode collector 7 with a fluororesin-based binder or a rubber-based binder 10.
