NONAQUEOUS ELECTROLYTE SECONDARY BATTERY, AND ADDITIVE AGENT FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERIES

摘要

PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery having a superior low-temperature characteristic.SOLUTION: A nonaqueous electrolyte secondary battery comprises: a positive electrode; a negative electrode; and a nonaqueous electrolytic solution including an electrolyte (F) and a nonaqueous solvent (G). In the nonaqueous electrolyte secondary battery, one or each of the positive electrode and the nonaqueous electrolytic solution includes a compound (E) having an urethane bond (c) and a polymerizable unsaturated bond (d); and the nonaqueous electrolytic solution includes a compound (H) expressed by the following chemical formula (1). [Chemical Formula(1)]. [In the formula(1), two R's each represent a hydrogen atom or a monovalent carbon hydride group having 1-10 carbon atoms, and the R's may be identical to each other or not; R's each represent a divalent carbon hydride group having 2-4 carbon atoms; n represents an integer of 1-5; and the plurality of R's may be identical to each other or not when n is equal to or larger than 2].
