【Summary description】Automotive power battery: In order to achieve a higher driving range of new energy vehicles, it is necessary to improve the energy density of the power battery. Because of the high aspect ratio of single-walled carbon nanotubes, the number of roots of single-walled carbon nanotubes is more than 10 times that of multi-walled carbon nanotubes at the same mass.
Automotive power battery: In order to achieve higher driving range of new energy vehicles, it is necessary to improve the energy density of the power battery. Because of the high aspect ratio of single-walled carbon nanotubes, the number of roots of single-walled carbon nanotubes is more than 10 times that of multi-walled carbon nanotubes at the same mass.
Therefore, it is possible to create extremely high conductivity and enhance network capabilities with very low additions, significantly improving the discharge power, energy density, adhesion, and safety of lithium batteries. In order to further increase the energy density of the battery, it is necessary to use silicon negative electrode and NCM 811 positive electrode materials in the battery. However, silicon negative electrode can cause volume expansion, thus affecting the cycle performance of the battery, single-wall carbon nanotubes are the key to solving the silicon negative electrode, due to its unparalleled conductivity, high strength, high flexibility, high aspect ratio, and the ability to form a developed network within the material at a low dose, single-wall carbon nanotubes can cover the surface of silicon particles after the introduction of silicon negative electrode. It also establishes highly conductive and long-lasting connections between silicon particles and significantly extends the cycle life of the negative electrode.
Heat dissipation material: Single-wall carbon nanotubes have extremely high thermal conductivity, and their thermal conductivity can reach 6000W/m.K, which is 10-20 times that of copper. It can therefore be used to:
1. Aircraft engine operation will produce extremely high heat, the temperature can reach 1400-1700℃, high requirements for heat dissipation, adding a single wall carbon nanotube thermal conductivity coating, thermal conductivity can be increased by more than 30%, can quickly reduce the temperature of the engine, improve the safety of operation.
2. When an aircraft flies through clouds with temperatures below zero, supercooled water droplets can form ice on surfaces such as wings, propellers, or engine air intakes, causing increased drag and significantly reducing lift, making the aircraft difficult to control. The excellent thermal conductivity of single-walled carbon nanotubes can be used for deicing, and lightweight resistance heaters based on carbon nanotubes (CNTs) can be used to prevent the icing and deicing of composite aircraft. When used on passenger aircraft using carbon fiber reinforced polymer composites (CFRP), the weight is negligible, the heating is fast and uniform, the energy consumption is low, the compatibility with CFRP is high, and the adjustment can be made to achieve rapid anti-freeze and de-icing.
Glass products: carbon nanotube glass with its excellent performance advantages, with high wear resistance and thermal conductivity, good anti-static effect and other excellent properties, can shield radio waves, better impact resistance, anti-static, wear resistance, high stability, not easy to affect the environment, safe and environmental protection.
Anti-static silicone touch screen: single-wall carbon nanotubes have extremely high mechanical properties and electrical conductivity, can be used as a flexible touch screen, flexible, high bending resistance, knock and scratch resistance, conductive anisotropy, can design a new principle of touch screen. Antistatic silicone for use in pressure-sensitive adhesive films.
Reinforced plastic: carbon nanotubes with its unique mechanical properties, improve the performance of traditional carbon fiber matrix composite materials, while high specific strength, high modulus, can reduce the weight of equipment components, improve the stiffness of equipment components, make full use of the characteristics of carbon nanotubes composite materials, make it harder, lighter weight, so as to expand the application of composite materials.
