Abstract

An electrolyte capable of improving battery characteristics even at high temperatures, a battery including the electrolyte, and a method for manufacturing an electrolyte are provided. The electrolyte contains at least one type of compound represented by the following formula:where R1, R2, R3, and R4 independently represent a hydrogen group, a fluorine group, a methyl group, an ethyl group, or a group in which a fluorine group has substituted for a part of the methyl group or the ethyl group; at least one of R1, R2, R3, and R4 is a group containing fluorine (F); and X, Y, and Z independently represents sulfur (S) or oxygen (O) except the case in which all of X, Y, and Z are oxygen (O), that is, X=Y=Z=O.
