Kind Code:

A1

Abstract:

Provided is an electrolytic solution with which it is possible to obtain a module or an electrochemical device such as a lithium-ion secondary cell in which generation of gas is less likely to occur even when stored in a high temperature and in which a high-capacity retention ratio is obtained even after high-temperature storage. An electrolytic solution characterized in containing a compound indicated by general formula Y21R21C-CY22R22 (where R21 and R22 may be identical or different and are H, an alkyl group, or a halogenated alkyl group; Y21 and Y22 may be identical or different and are -OR23 or a halogen atom; and R23 is H, an alkyl group, or a halogenated alkyl group), etc.
