    The Properties And Application of expanded graphite

    Expanded graphite is an adsorbent with excellent performance, especially it has a loose porous structure and strong adsorption capacity for organic compounds. 1 g of expanded graphite can absorb 80 g of petroleum, so expanded graphite is designed to be a variety of industrial greases and Adsorbent for industrial oils.

    The structural composition and physical and chemical properties of graphite

    Graphite is a transition type crystal between atomic crystals, metal crystals and molecular crystals. In the crystal, the carbon atoms in the same layer are sp2 hybridized to form a covalent bond. Each carbon atom is connected to three other carbon atoms. The six carbon atoms form a regular hexagonal ring on the same plane and stretch to form a sheet structure. . The carbon atoms in the same plane still have a p orbital each, they overlap each other, and the delocalized π-bonded electrons can move freely in the lattice and can be excited, so graphite has metallic luster, can conduct electricity and transfer heat. Due to the large distance between the layers and the small bonding force (Van der Waals force), each layer can slide, so the density of graphite is smaller than that of diamond, soft and smooth.

    The application prospect of carbon nanotubes

    Carbon nanotubes (CNTS) have the properties of being as hard as a diamond but very flexible, which can be stretched. At present, the critical factor for the strength of the enhanced fibers commonly used in the industry is the length-diameter ratio, which means the ratio of length to diameter. Typically, materials engineers want a rate of at least 20:1, while the proportion of carbon nanotubes is more than 1,000:1 usually.3. Prospect

    Ideal lithium battery anode material

    Lithium battery anode materials are currently the most critical link in the lithium-ion battery industry. According to the proportion of lithium-ion battery costs, negative electrode materials account for 25% to 28% of the total cost of lithium batteries. Compared with lithium battery cathode materials, research on anode materials has just begun.
