The present application provides an electrolytic solution and an electrochemical device. The electrolytic solution contains an additive A and an additive B, and the content of the additive A in the electrolytic solution is 0.001 to 10% by mass. The content of the additive B is 0.1 to 10% by mass. The present application can improve the cycle performance and storage performance of the electrochemical device, and in particular, can improve the cycle performance and storage performance of the electrochemical device under high temperature and high voltage.
