Abstract: This application provides a non-aqueous electrolyte and a preparation method thereof, and a secondary battery and an electric apparatus containing the same. The non-aqueous electrolyte contains the non-aqueous solvent and lithium ions, first cations, and first anions dissolved therein, where the first cation is a metal cation Men+ other than the lithium ion, n representing a chemical valence of the metal cation; the first anion is a tetrafluoroborate anion BF4?; mass concentration of the first cations in the non-aqueous electrolyte is D1 ppm, and mass concentration of the first anions in the non-aqueous electrolyte is D2 ppm, both based on total mass of the non-aqueous electrolyte; and the non-aqueous electrolyte satisfies that D1 is 0.1 to 1250 and that D1/D2 is 0.02 to 2. The non-aqueous electrolyte in this application enables the secondary battery to have good cycling performance, safety performance, and kinetic performance.

Abstract: A video processing method and apparatus, and an electronic device and a storage medium are provided. The method comprises: receiving a trigger operation acting on a target guide control of a video posting interface; and in response to the trigger operation, adding a target guide sticker to the current video to be posted, so as to display the target guide sticker during the playing process of said current video.

Abstract: A video processing method and apparatus, an electronic device, and a storage medium are provided.
