    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

    Lithium-ion battery anode material main force: graphite material

    As one of the four primary materials for lithium-ion batteries, the specific capacity and operating voltage directly determine the energy density and operating voltage of the battery. Although silicon materials have gradually begun to industrialize, the current mainstream anode materials are still graphite. The negative electrode material has a low lithium insertion potential during the reaction, and the lithium intercalation compound generated at the same time replaces the metal lithium negative electrode, thereby avoiding the deposition of metal lithium dendrites, so the safety is significantly improved.

    Advantages and disadvantages of graphite anode materials for lithium ion batteries

    Advantages and disadvantages of graphite anode materials for lithium ion batteries. The energy density of lithium ion battery depends on the anode material to a large extent. From the commercialization of lithium ion battery to now, the anode material used is the most mature and the most widely used is carbon material, among which the most important one is still graphite. When graphene is directly used as anode material for lithium batteries, it has very considerable electrochemical properties.

    Development History of Carbon Nanotubes

    Carbon nanotubes are one-dimensional quantum materials with unique structures (radial dimensions are on the order of nanometers, axial dimensions are on the order of micrometers, and the ends of the tube are sealed). Carbon nanotubes are mainly coaxial tubes composed of carbon atoms arranged in hexagons, ranging from several layers to tens of layers. A fixed distance is maintained between the sheets, about 0.34 nm, and the diameter is generally 2-20 nm. And according to the different orientations of the carbon hexagon in the axial direction, it can be divided into three types: zigzag, armchair, and spiral. Carbon nanotubes, as one-dimensional nanomaterials, are lightweight and have a hexagonal structure with perfect connections. They have many unusual mechanical, electrical, and chemical properties.
