Abstract: A battery electrolyte solution contains a lithium salt dissolved in a solvent phase comprising at least 10% by weight of ethyl (2,2,3,3-tetrafluoropropyl) carbonate. The solvent phase comprises optionally other solvent materials such as 4-fluoroethylene carbonate and either or both of diethyl carbonate and ethyl methyl carbonate. This battery electrolyte is highly stable even when used in batteries in which the cathode material has a high operating potential (such as 4.5V or more) relative to Li/Li+. Batteries containing this electrolyte solution therefore have excellent cycling stability.
