Document Type and Number:
WIPO Patent Application WO/2021/017709
Kind Code:
A1
Abstract:
An electrolyte, an electrochemical device including the same and an electronic device are provided. The electrolyte comprises one or more nitrile benzoquinone compounds selected from the group consisting of the compounds represented by formula I, formula II, and formula III wherein the substituents R 1 to R 9 are each independently selected from the group consisting of hydrogen, a C2 to C12 ether group, a C1 to C12 alkoxy group, halogen, a C1 to C12 alkyl group, a C2 to C12 alkenyl group, a C2 to C12 alkynyl group, and a C6 to C26 aryl group. The electrolyte can form a stable protective film on a cathode, thereby increasing the cycle capacity retention rate and high temperature storage performance of the electrochemical device.
