NONAQUEOUS ELECTROLYTE SECONDARY BATTERY AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery superior in output characteristic in a low SOC and excellent in durability.SOLUTION: A nonaqueous electrolyte secondary battery comprises: a positive electrode current-collecting core material; and a sheet body including granulated materials. The sheet body is disposed on the positive electrode current-collecting core material. The granulated materials include: first positive electrode active material particles including a lithium nickel complex oxide; second positive electrode active material particles including lithium iron phosphate; and expanded graphite.
