Abstract: In order to overcome the problems of insufficient storage performance and cycle performance of existing lithium ion batteries, the present application provides an electrolyte, comprising a solvent, a lithium salt and an additive, wherein the additive comprises vinylene carbonate, 3,3?-[1,2-ethylenebis (oxy)] dipropionitrile and lithium difluoro (oxalate) borate, and a weight ratio of vinylene carbonate, 3,3?-[1,2-ethylenebis (oxy)] dipropionitrile and lithium difluoro (oxalate) borate is 1:0.2-6:0.01-5. Meanwhile, the application also discloses a lithium ion battery comprising the above electrolyte. The electrolyte provided by the present application can effectively improve the high-temperature storage performance and cycle performance of batteries.

Abstract: The present disclosure provides a method, an apparatus, an electronic device, and a readable storage medium for detection of vehicle traveling state. The method may include obtaining a frequency of an emitted microwave from a microwave sensor and a frequency of a reflected microwave received by the microwave sensor. The microwave sensor may be located at a vehicle head of a vehicle. The method may also include obtaining a running speed of the vehicle. The method may further include determining, according to the frequency of the emitted microwave, the frequency of the reflected microwave, and the running speed, whether the vehicle is traveling in a wrong direction.
