POSITIVE ELECTRODE FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY AND MANUFACTURING METHOD THEREOF, AND NON AQUEOUS ELECTROLYTE SECONDARY BATTERY AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a positive electrode for a nonaqueous electrolyte secondary battery and a manufacturing method thereof wherein cost increase and reduction of productivity can be suppressed while improvement of cycle characteristics and storage characteristics (especially both characteristics at high temperatures) can be improved.

SOLUTION: In the positive electrode for the nonaqueous electrolyte secondary battery having a positive electrode current collector 2 and a positive electrode active material layer 1 which is formed on a surface of this positive electrode current collector 1 and contains positive electrode active material particles and a binder, TiO2particles 3 are contained in the positive electrode active material layer 1. These TiO2particles 3 are eccentrically located in the vicinity of a surface of the positive electrode active material layer 1.
