Document Type and Number:
Japanese Patent JP5692219
Kind Code:
B2
Abstract:
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 R 1 and R 2 each represent a hydrogen atom, or an alkyl group having from 1 to 6 carbon atoms; X 1 represents a group selected from -S(=O)-, -S(=O) 2 -, - C(=O)-, -CR 3 R 4 -, -P(=O)(OR 5 )- and -SiR 6 R 7 -; R 3 and R 4 each represent a hydrogen atom, or an alkyl group having from 1 to 6 carbon atoms; R 5 to R 7 each represent an alkyl group having from 1 to 6 carbon atoms. Y 1 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; Z 1 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 X 1 , Y 1 and Z 1 may be substituted with a halogen atom).
