Abstract

The present application provides an electrolyte and an electrochemical device. The electrolyte according to the present application comprises a carboxylate, a barbituric acid compound and a nitrile compound. Adding a barbituric acid compound and a nitrile compound of particular structure to an electrolyte containing a carboxylate solvent can significantly improve the rate performance of an electrochemical device, and mitigate capacity loss after storage at room temperature, and cycle fading and gas generation at high-temperature of the electrochemical device.
