- graphene - producing a carbon composite material

The present invention discloses a lithium ion battery peach-like graphene SnO2- - producing a carbon composite material, tin composite salt as a raw material, graphene oxide as the carrier, both the ultrasound after mixing, stirring and spray preparing a composite material precursor, and then the hot water after mixing the precursor solution was prepared with the carbon composite material. Peach-like carbon coating prepared according to the method of the tin-based composite material SnO2 particles are loaded onto the graphene, and then coated with a layer of a carbon layer on the outside, the whole structure presentation peach-like, such a structure can be better constrained tin oxide particles change in volume, so that a material having more excellent cycle characteristics.
