Patent ID: 8389164

Claim:
A nonaqueous electrolytic solution comprising an electrolyte salt dissolved in a nonaqueous solvent, wherein the nonaqueous electrolyte solution contains at least one compound selected from the group consisting of a chain compound having a hydroxyl group and a carbon-carbon double bond, a light metal alkoxide thereof and a derivative thereof obtained by substituting the hydroxyl group with a protective group, and wherein the chain compound have a hydroxyl group and a carbon-carbon double bond, the light metal alkoxide thereof or the derivative thereof obtained by substituting the hydroxyl group with a protective group is any one of compounds represented by the following formulae (1) to (6): wherein each of R and R1 represents a hydrogen atom, a halogen atom, a vinyl group, an alkyl group having from 1 to 4 carbon atoms or a halogenated alkyl group having from 1 to 4 carbon atoms in which at least one hydrogen atom is substituted with a halogen atom, and R and R1may be the same as or different from each other; R2 represents a methyl group, an ethyl group, an isopropyl group, a tertiary butyl group or a phenyl group, and each R2 may be the same as or different from every other R2; R3 represents a hydrocarbon group having from 1 to 10 carbon atoms or a hydrocarbon group having from 1 to 10 carbon atoms, a part of which is substituted with a functional group containing a hetero element inclusive of oxygen (O) or silicon (Si); R4 represents a methyl group, a tertiary butyl group or an aryl group; M represents an alkali metal element; each of a, b and c represents an integer of from 0 to 5 and satisfies the relationship of {1≦(a+2b+c)≦5}; each of d, e and f represents an integer of from 0 to 4 and satisfies the relationship of {1≦(d+2e+f)≦4}; and g represents an integer of from 1 to 5.
