Few-layer graphene preserves the original crystal structure, characteristics and other properties of natural flake graphite. It is large in shape (diameter/thickness ratio), and has excellent electrical, thermal, and mechanical properties. Excellent electrical conductivity, lubrication resistance, corrosion resistance and other characteristics. The specific surface of the graphene layers is 400700m2/g. The thickness is 0.553.74nm. Graphene has a high surface specificity. It can be mixed easily with other materials like polymers to create a good interface.

As an excellent base material for industrial-scale functional composites materials, graphene layers will play a crucial role in this new industrial revolution. These graphene flakes can be attached with inorganic particles to stop them being stacked multiple times during chemical reduction. It can also encourage the formation of new materials with graphene carriers. The graphene inorganic nanocomposites have excellent performance. They can be widely utilized in sensors, supercapacitors batteries, batteries, catalysis, and other fields. These outstanding properties can dramatically improve the performance nanomaterials.
Few-layer graphene offers great utility in the energy sector. It is also very useful in supercapacitors, 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. The supercapacitors’ large surface area and excellent conductivity are conducive for nanoparticle dispersion. This facilitates electron transfer from nanoparticles into the graphene matrix. This is known as the passive film phenomenon. This is an effect that improves the battery’s cycle performance. Using graphene in place of traditional graphite materials for lithium-ionbatteries will increase the lithium storage potential of the negative electro. In addition, the graphene material contains lithium ions. The diffusion path is short and conductivity high, which can dramatically improve the rate performance. For hydrogen storage, some atoms (such transition metals, alkali metallics) are first absorbed on graphene. The adsorption is the charge transfer that occurs between the increased and substrate atoms. This alters the local charge density which greatly increases the adsorption of graphene for hydrogen.
