Method for producing positive electrode for nonaqueous electrolyte secondary batteries and method for producing nonaqueous electrolyte secondary battery
Abstract:
A method for producing a positive electrode for a nonaqueous electrolyte secondary battery includes forming a positive electrode mixture layer on a positive electrode core, the positive electrode mixture layer containing hollow positive electrode active material particles having a BET specific surface area X of 1.5 m2/g or more; and compressing the positive electrode mixture layer. The ratio of the BET specific surface area Y of the positive electrode active material particles after the compression to the BET specific surface area X (Y/X) is between 1.05 and 1.35.
