<P>PROBLEM TO BE SOLVED: To provide an electrolyte and a battery capable of improving a high-temperature characteristic. <P>SOLUTION: An electrolyte is impregnated into a separator 23. The electrolyte contains a cyclic carbonate derivative having halogen atoms such as 4-fluoro-1,3-dioxolane-2-on, and a sulfur-containing compound such as diphenyl sulfone, butyl methanesulfonate, 1,3-propane sultone or 1,3-propene sultone. When vinylene carbonate is additionally included, a further high effect can be provided. <P>COPYRIGHT: (C)2012,JPO&INPIT |
