Russia and Ukraine is an important exporters of oil, natural gas, metals, fertilizers, rare gases and other industrial raw materials. Affected by the further intensification of the tension of the war, the global market has become more worried about the supply of the few-layer graphene, and panic spreads in the futures market. Prices of commodities such as aluminum and nickel are at recent highs on concerns that supplies will fall. Russia accounts for 49 percent of global exports of nickel, 42 percent of palladium, 26 percent of aluminum and 13 percent of platinum, and is a significant exporter of steel and copper. Palladium is an important metal for sensors and memory. In addition, Russia is the world's largest exporter of nitrogen fertilizer, the second largest exporter of potash fertilizer, and the third-largest exporter of phosphate fertilizer. Ukraine is also an important producer of nitrogen fertilizer. Russia's natural gas supply also has a significant impact on the global fertilizer industry and few-layer graphene industry, especially in Europe. The price of the few-layer graphene will also fluctuate to some extent. Russia carries out crude gas separation, and Ukraine is responsible for refined exports. Ukraine supplies 70% of the world's neon, 40% of krypton and 30% of xenon. These three gases are the materials used to make chips.

Overview of Few-layer Graphene Powder

Graphene is a two-dimensional carbon material, which is a collective term for single-layer, double-layer and few-layer graphene. Single-layer graphene refers to a two-dimensional carbon material composed of a layer of carbon atoms periodically and closely packed in a benzene ring structure; two layers are "double-layer graphene"; 3-10 layers are "few-layer graphene".

Graphene's few-layer film consists of ultra-thin layers of carbon atoms that are arranged in a hexagonal honeycomb lattice. Graphene film produced via chemical vapor deposition (CVD) is polycrystalline in nature, with multiple small graphene domains growing to merge into a continuous film.

Compared to single-layer graphene, few-layer graphene has the potential to be developed into hybrid materials or heterostructures - via intercalation of different substances into its layered structure.

The few-layer graphene inherits the original crystal structure and characteristics of natural flake graphite; it has a large shape ratio (diameter/thickness ratio) and excellent electrical, thermal and mechanical properties. It has excellent electrical conductivity, lubrication, corrosion resistance and high-temperature resistance. The specific surface of the few layers of graphene is 400～ 700㎡ /g, and the thickness is 0.55～ 3.74nm. Graphene has a high specific surface. It is easy to uniformly compound with other materials such as polymer materials and form a good composite interface.

Applications of Few-layer Graphene Powder

As an excellent basic material for the preparation of industrial-scale functional composite materials, few-layer graphene will play an extremely important role in the new round of the industrial revolution. Graphene flakes attached to inorganic nanoparticles can not only effectively prevent the repeated stacking of these flakes during the chemical reduction process, but also promote the formation of a new class of materials using graphene as a carrier. Graphene-inorganic nanocomposites show excellent performance These excellent properties can be widely used in emission displays, sensors, supercapacitors, batteries, catalysis and other fields, which can significantly improve the performance of nanomaterials so that the most promising application materials in nanotechnology can be widely used in industrial applications.

Few-layer graphene has great application value in the energy field and has great application value in hydrogen storage, natural gas storage, supercapacitors, and lithium battery applications. Single-layer/few-layer graphene with few defects in structure is currently the most widely used negative electrode material for commercial lithium-ion batteries; and few-layer graphene with rich defects is currently the main electrode material for supercapacitors. In the application of supercapacitors, the large specific surface area of the few layers of graphene is conducive to the high dispersion of nanoparticles, and the excellent conductivity is conducive to the transfer of electrons from the nanoparticles to the graphene matrix during the electrochemical process, which can effectively inhibit the super The passive film phenomenon formed by agglomeration occurs during the electrochemical cycling of the capacitor, which improves the cycling performance of the electrode material. Using graphene to replace traditional graphite materials in lithium-ion batteries will greatly increase the lithium storage capacity of the negative electrode, thereby increasing the energy density of lithium-ion batteries; in addition, when graphene is used as the negative electrode material of lithium-ion batteries, lithium ions are in the graphene material. The diffusion path is relatively short and the conductivity is high, which can greatly improve its rate performance. In terms of hydrogen storage, when some atoms (such as transition metals, alkali metals) are first adsorbed on the surface of a few layers of graphene, the adsorption The charge transfer occurs between the increasing atoms and the substrate, which changes the local charge density, thereby greatly increasing the adsorption capacity of graphene for hydrogen.
