Abstract

The invention discloses a preparation method of a thin layer graphene polymer composite material. The method includes enabling a graphite intercalation compound and / or thin layer graphene with a catalyst adsorbed on the surface and at least one polymer monomer to form a mixed reaction system and conducting catalytic polymerization reaction under the set condition to obtain the thin layer graphene polymer composite material. An intercalation agent in the graphite intercalation compound and the catalyst are at least selected from any one of inorganic acid, organic acid, halogen, metal salt and metal oxide. The preparation method is simple in process, easy to implement, safe, environment-friendly, low in cost and suitable for industrial batch production. Further, the obtained composite material can be applied to lithium ion battery electrode materials or super capacitor electrode materials.

Description

technical field

[0001] The invention specifically relates to a preparation method of a thin-layer graphene polymer composite material, which belongs to the technical field of nanomaterials. Background technique

[0002] Energy storage devices mainly include supercapacitors and lithium-ion batteries. An important part of an energy storage device is the electrode, and the material and structure of the electrode have a significant impact on the performance of the energy storage device. Taking a supercapacitor as an example, when a conductive polymer is used as an electrode, its storage charge density is high, and the reversible doping of the conductive polymer during the charge and discharge process makes it have a high charge storage capacity. Compared with metal oxide electrodes, conductive polymers have the advantages of cheap price and adjustable structure, but the conductive polymers are not brittle and their strength is not high, resulting in poor cycle stability of capa...
