NONAQUEOUS ELECTROLYTE SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To obtain a nonaqueous electrolyte secondary battery capable of suppressing reduction of remaining capacity and return capacity when carrying out continuous charge under a high voltage and a high temperature.

SOLUTION: The nonaqueous electrolyte secondary battery includes: a positive electrode; a negative electrode; and a nonaqueous electrolytic solution. Ethylene carbonate and fluoroethylene carbonate are contained as solvents in the nonaqueous electrolytic solution, and a positive electrode active material adhered to a surface in a state that particulates of a rare-earth element compound are dispersed is contained in the positive electrode.
