Abstract
The present application relates to an electrolyte, and an electrochemical device comprising the electrolyte. The electrolyte comprises a fluorinated cyclic carbonate and a multi-nitrilemulti-nitrile compound having an ether bond, wherein based on the total weight of the electrolyte, the weight percentage (Cf) of the fluorinated cyclic carbonate is greater than the weight percentage (Cn) of the multi-nitrilemulti-nitrile compound having an ether bond. The electrolyte of the present application can control the expansion of the electrochemical device, so that the electrochemical device has excellent cycle, storage and/or floating-charge performance.
