A few-layer graphene preserves the crystal structure and properties of natural flake graphite. Excellent electrical conductivity, lubrication and corrosion resistance. The thickness of graphene layers is 0.553.74nm. Graphene exhibits a high surface specificity. It’s easy to combine graphene with other materials, such as polymers materials, and create a strong compound interface.

As an ideal base material for industrial-scale production of functional composite materials at industrial scale, graphene layers will only be a few. This is an essential role in this new industrial revolution. The attachment of graphene flakes to inorganic particles can prevent the flakes being repeated stacked during the chemical reduction process. The graphene-inorganic nanoparticles can be used to promote the development of a new type of material with graphene. The graphene inorganic nanocomposites have excellent performance. They can be widely utilized in sensors, emission displays, supercapacitors batteries and catalysis.

Very few-layer graphene is very valuable in the energy sector. This material has great potential for use in hydrogen storage, natural gas storage and in lithium battery applications. Single-layer/few-layer graphene with fewer defects in structure is currently the most widely used negative electrode material for commercial lithium-ion batteries; and defect-rich, few-layer graphene is currently the main electrode material for supercapacitors. A large area of graphene in supercapacitors is favorable to dispersion of nanoparticles. It also allows for the electron transfer to the graphene matrix from the nanoparticles during the electrochemical cycling of the capacitor. Utilizing graphene as a replacement for traditional graphite in lithium-ion lithium batteries will significantly increase their lithium storage capacities. This can lead to a higher energy density. Additionally, the graphene used in negative electrodes of lithium-ion lithium batteries means that lithium ions remain in graphene. This can significantly improve the rate performance of lithium-ion batteries as its diffusion path is short and conductivity high. For hydrogen storage, some atoms (such transition metals or alkali metallics) will first be adsorbed to graphene. Then, there is the charge transfer. This alters the local charge density and greatly enhances the graphene’s ability to absorb hydrogen.
