1)SWCNT Structure, Performance, Applications


At present, conductive additives are one of the largest application directions of carbon nanotubes In the lithium battery industry, carbon nanotubes are already commonly used electrode conductive agents.

Single-walled carbon nanotubes are one-dimensional quantum materials made of single-walled graphene layers curled around the central axis at a certain spiral angle.
The length-diameter ratio and carbon purity of single-walled carbon nanotubes are the two core indicators affecting conductivity. It directly determines the product performance of carbon nanotubes, and the thinner the diameter and length of carbon nanotubes, the better the conductivity.


  • MECHANICAL PROPERTIES:Single-walled carbon nanotubes have extremely high strength, with extremely high elasticity and toughness Young''''''''''''''''s modulus is nearly 6 times that of steel, and the tensile strength is 100 times that of steel.
  • THERMAL    PROPERTIES:A single carbon nanotube has extremely high thermal conductivity, with a theoretical value of up to 6000W/mk at room temperature.
  • ELECTRICAL PROPERTIES:SWCNTs have excellent electrical conductivity when embedded in a material matrix. With a very small amount of addition, single-walled carbon nanotubes can form a three-dimensional conductive network.


Single-walled carbon nanotubes have a high aspect ratio and excellent electrical conductivity, which can improve the energy density of lithium batteries and extend the cycle life of batteries





The excellent performance of single-walled carbon nanotubes can meet the development needs of power lithium batteries


For the next generation of silicon-based anodes, single-walled carbon nanotubes can significantly improve their cycling performance

Based on the excellent characteristics of single-walled pipes, after the introduction of silicon anode, silicon particles can be effectively coated and establish a stable conductive bridge between the particles. Thus, it effectively compensates for the lack of conductivity and volume expansion effects of silicon atoms themselves.
