ELECTROCHEMICAL DEVICE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/121294
Kind Code:
A1
Abstract:
An electrochemical device and an electronic device. The electrochemical device comprises a positive electrode, a negative electrode, and an electrolyte. The electrolyte comprises: fluoroethylene carbonate and non-fluorinated cyclic carbonate, the percentage by mass of the fluoroethylene carbonate accounting for the mass of the electrolyte is a%, the percentage by mass of the non-fluorinated cyclic carbonate accounting for the mass of the electrolyte is b%, and 0.05≤a/b≤2.5. The electrochemical device has improved cycle performance, and reduces direct-current impedance.
