摘要:
An object of the present invention is to provide a nonaqueous electrolytic solution capable of improving low-temperature load characteristics after high temperature charging storage, an electrochemical element using it, and a 1,2-dioxypropane compound used for it.The nonaqueous electrolytic solution of the present invention comprises an electrolyte salt dissolved in a nonaqueous solvent, and contains a 1,2-dioxypropane compound represented by the above-mentioned general formula (I). (wherein R1 and R2 each represent a hydrogen atom, or an alkyl group having from 1 to 6 carbon atoms; X1 represents a group selected from —S(═O)—, —S(═O)2—, —C(═O)—, —CR3R4—, —P(═O)(OR5)— and —SiR6R7—; R3 and R4 each represent a hydrogen atom, or an alkyl group having from 1 to 6 carbon atoms; R5 to R7 each represent an alkyl group having from 1 to 6 carbon atoms. Y1 represents an alkylsulfinyl group, an alkenylsulfinyl group, an alkynylsulfinyl group, an arylsulfinyl group, an alkylsulfonyl group, an alkenylsulfonyl group, an alkynylsulfonyl group, or an arylsulfonyl group; Z1 represents a hydrogen atom, an alkyl group, an alkylsulfinylmethyl group, an alkenylsulfinylmethyl group, an alkynylsulfinylmethyl group, an arylsulfinylmethyl group, an alkylsulfonylmethyl group, an alkenylsulfonylmethyl group, an alkynylsulfonylmethyl group, or an arylsulfonylmethyl group; provided that at least one hydrogen atom on the carbon atom of X1, Y1 and Z1 may be substituted with a halogen atom).
