Provided is an electrolyte making it possible to accommodate an increase in voltage in an electrochemical device, improve high-temperature storage characteristics of the electrochemical device to a greater extent than conventional electrolytes, and minimize gas generation during high-temperature storage. The electrolyte is characterized in containing a sultone derivative, an electrolytic salt, and a solvent containing a fluorinated chain carbonate having a fluorine content of 33-70 mass%. |
