ABSTRACT:
There is provided an electrolytic solution comprising a fluorine-containing cyclic carbonate (I) represented by the formula (I):wherein Rf1is a fluorine-containing ether group (Ia), a fluorine-containing alkoxyl group (Ib) or a fluorine-containing alkyl group (Ic) having two or more carbon atoms; X1and X2are the same or different and each is H, F, Cl, CF3or CH3; X3is H, F, Cl or an alkyl group in which hydrogen atom may be substituted with halogen atom and hetero atom may be contained in its chain, and an electrolyte salt (II). The electrolytic solution is excellent in flame retardance, low temperature characteristics and withstand voltage, high in solubility of an electrolyte salt and excellent in compatibility with a hydrocarbon solvent.
