The present application provides electrolytes, electrochemical devices, and electronic devices. The electrolyte includes fluorine-containing lithium salt and lithium dicyanamide, and the fluorine-containing lithium salt includes lithium fluorosulfonyl (trifluoromethylsulfonyl)imide. The embodiments of the present application improve the electrolyte, so that the lithium salt includes lithium fluorosulfonyl (trifluoromethylsulfonyl)imide and lithium dicyanamide, which is beneficial to enhance the stability of the solid electrolyte interface (SEI) film of the negative electrode Therefore, the cycle performance of the electrochemical device is improved, and the kinetic performance of the electrolyte is basically not affected. |
