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

MoreIdeal 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.

MoreLithium battery anode material standard
Lithium-ion batteries have many advantages such as high energy density, long cycle life, small self-discharge, no memory effect and environmental friendliness. They have been widely used in consumer electronics fields such as smartphones, smart bracelets, digital cameras and notebook computers. With the most significant consumer demand. At the same time, it is gradually being promoted in the field of pure electric, hybrid electric and extended-range electric vehicles, and the market share growth trend is the largest. In addition, lithium-ion batteries also have a good development trend in large-scale energy storage fields such as power grid peaking, home power distribution and communication base stations.

MoreLithium-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.

MoreAdvantages 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.

MoreDevelopment 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.
