Abstract
The present application relates to an electrolyte, an electrochemical device and an electronic device comprising the same. The electrolyte of the present application includes a cyclic N-containing sulfonyl-compound and at least one of vinylene carbonate, fluoroethylene carbonate, lithium tetrafluoroborate, lithium difluoro(oxalato)borate or lithium difluorophosphate. The electrolyte of the present application may further include a sulfur-oxygen double bond containing compound and a silicon-containing carbonate. Compared with the prior art, using the electrolyte provided by the present application can effectively improve the high-temperature storage, cycle performance and overcharge performance of an electrochemical device, such as a lithium-ion battery.
