Document Type and Number:
WIPO Patent Application WO/2022/141047
Kind Code:
A1
Abstract:
Provided in the present application is an electrolyte, an electrochemical apparatus, and an electronic apparatus, wherein the electrolyte comprises at least one among compounds represented by formula (I-A); in formula (I-A), A1, A2, A3, and A4 are each independently selected from any one among structures represented by formula (I-B), formula (I-C), formula (I-D), or formula (I-E). More stable positive and negative electrode protective film generation is able to be promoted by means of adding a formula (I-A) compound that possesses a special function into an electrolyte, a side reaction and impedance growth are effectively inhibited, direct current impedance after a high voltage cycle of an electrochemical apparatus is effectively reduced, and the cycle performance of the electrochemical apparatus is improved.
