Title:
ELECTROLYTIC SOLUTION FOR NONAQUEOUS ELECTROLYTIC SOLUTION BATTERY, AND NONAQUEOUS ELECTROLYTIC SOLUTION BATTERY USING SAME
Document Type and Number:
WIPO Patent Application WO/2017/138452
Kind Code:
A1
Abstract:
This electrolytic solution for a nonaqueous electrolytic solution battery comprises: (I) at least one type of silane compound represented by general formula (1); (II) at least one type of compound from cyclic sulfonic acid compounds and cyclic sulfate ester compounds; (III) a nonaqueous organic solvent; and (IV) a solute. The electrolytic solution can achieve, in a balanced manner, an improvement in high-temperature storage properties at 70°C or higher, and the effect of reducing the amount of gas produced during high-temperature storage. (In general formula (1), R1s each independently represent a group including a carbon-carbon unsaturated bond; R2s are each independently selected from a fluorine group or a C1-10 linear or C3-10 branched alkyl group, wherein the alkyl group may include a fluorine atom and/or an oxygen atom; and x is from 2 to 4.)
