Abstract
A non-aqueous mixture solvent for a non-aqueous electrolytic solution to be used for electrochemical energy devices, which contains an aprotic solvent, and a fluorinated ketone of the formula: (wherein Rf1 and Rf2 each independently represents a fluorinated aliphatic group, or Rf1 and Rf2 together form a cyclic group, Q represents a fluorinated or non-fluorinated alkylene group or a bond, and n represents 0 or 1), and an electrolytic solution containing the mixture solvent.
