NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a high output type non-aqueous electrolyte secondary battery with high performance which has an insulation structure between a positive electrode and a negative electrode optimized and has little deterioration even if high output discharge is repeated while maintaining the initial output characteristics.

SOLUTION: The non-aqueous electrolyte secondary battery includes a positive electrode, a negative electrode, a fine porous separator made of resin, and a non-aqueous electrolytic liquid. The area per theoretical capacity of the positive electrode is made 190-800 cm2/Ah and a porous heat resistant layer with a thickness of 10-60 μm is arranged between at least one of the positive electrode and the negative electrode and the separator.
