摘要： PROBLEM TO BE SOLVED: To provide a lithium ion secondary battery which includes a separator superior in oxidation resistance and makes both superior reliability and safety compatible even when carrying out charging at a higher voltage than before. SOLUTION: The lithium ion secondary battery is equipped with a positive electrode 11 and a negative electrode 12 capable of reversively storing/releasing lithium, a separator 13 arranged between the positive electrode 11 and the negative electrode 12, a battery case to house the positive electrode 11, the negative electrode 12, and the separator 13, and a nonaqueous electrolytic solution filled into the battery case. The separator 13 has ultrahigh molecular weight polyethylene of 500,000 or more of the weight average molecular weight as the main component, and contains polyolefin resin composition obtained by chemically cross-linking ultra-high molecular weight polyethylene, polynorbornene, and grafted polyethylene, and gel fraction of the polyolefin resin composition is 42% or more and 57% or less.

摘要： PROBLEM TO BE SOLVED: To provide a nonaqueous solvent and a nonaqueous electrolyte for a power storage device, which are highly resistant to oxidation. SOLUTION: The nonaqueous solvent for the power storage device is expressed by a general formula (1), and includes a fluorine-containing cyclic saturated hydrocarbon having a configuration with one or two substituent(s) R being introduced to a cyclohexane ring (in the general formula (1), R is expressed by C n X 2n+1 , where n is an integer equal to or larger than 1, one of 2n+1 Xs is F, and other Xs are F or H), a chain sulfone compound expressed by a general formula (2) (in the general formula (2), each of R 1 , R 2 is an independent 1C-4C alkyl group, respectively), and a cyclic sulfone compound expressed by a general formula (3) (in the general formula (3), X is an alkylene group with a carbon number 1 to 7, which may be a straight chain or may have a branch).
