Abstract: A composite negative electrode sheet, a preparation method thereof, and a lithium ion battery using the same are provided. The composite negative electrode sheet includes a current collector, an active coating and an insulation coating that are disposed in sequence. The insulation coating includes a polymer, an inorganic filler, and a fast ion conductor, the active coating includes a binder and an active material, and a solubility parameter difference between the polymer and the binder is expressed as |??| that is greater than 0.5 (J/cm3)1/2.

Abstract: The media stream transmission method includes: receiving a first request for media data from a first terminal; determining a second request according to downlink information and transmitting the second request to a second terminal; where the downlink information is configured to indicate request load information and/or downlink network quality-of-service information, the request load information represents a quantity and/or frequency of a plurality of third requests received within a preset time period, and the plurality of third requests include the first request; receiving, from the second terminal, a first media data message being a response to the second request; where the first media data message includes a first media stream; and transmitting, to the first terminal, a second media data message being a response to the first request, where the second media data message includes a second media stream, and the first media stream includes the second media stream.
