1.Problems of graphene dispersion Graphene has a single complete six membered ring structure, so there is a strong intermolecular force between graphene molecules, and the layers are easy to stack together, resulting in agglomeration. The surface of graphene is stable and inert, which makes it difficult to dissolve in basic solvents, and it is very

Lithium ion battery is the most popular circulating battery because of its high voltage and high specific energy. Graphene is a unique nano material, with unique network structure, multi-stage pore structure and excellent electrical properties, which can greatly improve the battery capacity and has a broad economic prospect. MIT has developed a new flexible and

1. Graphene raw materials: natural graphite, artificial graphite, expanded graphite, such as graphite raw materials finishing and equipment. 2. Graphene powder materials: oxidation and reduction of large-scale preparation of graphene powder, preparation of graphene nano-flakes or graphene flakes, graphene quantum dots, oxidized graphene solutions, graphene solutions, activated graphene, porous graphene, functional graphene, oxidized graphite sheets, graphene

Graphene is one of the most important compounds in the world ² The hybrid connected carbon atoms are closely packed to form a single layer of two-dimensional honeycomb lattice structure. Graphene has excellent optical, electrical and mechanical properties. It has important application prospects in materials science, micro nano processing, energy, biomedicine and drug delivery. It

With the development of science and technology, human resources will be used less and such as oil, forests, all kinds of minerals, with a little less than a day. These resources are mined, mined, and much larger than the growth of resources, so resources will be used less and more expensive. The development and research

The French researchers reported that the more irregular carbon materials used to make supercapacitor electrodes, the greater the capacitance of the supercapacitor is and the stronger the ability to withstand high pressure. Supercapacitor is a new type of energy storage device, which has the advantages of short charging time, high output power, long life and
