Description

technical field [0001] The invention relates to the technical field of graphene coils, in particular to a novel copper-based graphene coil. Background technique [0002] Graphene is a new material with a single-layer sheet structure composed of carbon atoms. It is a planar film composed of carbon atoms with sp2 hybrid orbitals forming a hexagonal honeycomb lattice, a two-dimensional material with a thickness of only one carbon atom. Graphite film is mainly produced in the form of flakes, which brings inconvenience to the later die-cutting process. The characteristic is that the actual utilization rate of the material cannot be improved, and the graphite film needs to be pasted one by one on the sheet before die-cutting. Protective film or electrostatic film to form a roll structure, and then cut. [0003] The existing application number is CN 201621453891.7.

Graphite film is mainly produced in the form of flakes, which brings inconvenience to the later die-cutting process.

Protective film or electrostatic film to form a roll structure, and then cut

[0003] The existing application number is CN 201621453891.7. A copper-based graphene composite film coil is provided with a pressing convex line on the copper-based graphene composite film. When pressing and forming, the pressing convex line is deformed under the action of pressure. Pressing into the electrostatic film improves the stability of the pressing and makes the pressing more firm, but it does not do a large protective treatment for the body of the copper-based graphene coil, which will cause the formation of the copper-based graphene to be relatively slow. Moreover, the strength of the copper-based graphene coil is not enough, and it is easy to be damaged and broken
