Nonaqueous solvent and nonaqueous electrolytic solution for electricity storage device and nonaqueous electricity storage device, lithium secondary battery and electric double layer capacitor using the same

摘要

A nonaqueous solvent for an electricity storage device according to the present invention comprises fluorine-containing cyclic saturated hydrocarbon having a structure which is represented by general formula (1) below and in which one or two substituents R are introduced into a cyclohexane ring (in general formula (1), R is represented by CnX2n+1, n is an integer of 1 or greater, at least one of (2n+1) pieces of X's is F, and the other X's are F or H).
