Multi-walled carbon nanotube MWCNT powder for conductive resin

Carbon nanotubes can reduce electrode impedance as a conductive agent. Carbon nanotubes have a very high aspect ratio, large specific area, better thermal conductivity, and a medium structure that is conducive to lithium ion embedding, forming a large number of conductive contact points with active material particles, reducing electrode impedance. Due to the high cleanliness, good one-dimensional structure, and cylindrical microstructure of carbon nanotubes, they show better quality.

Carbon nanotubes can be used as a conductive agent to build a smooth three-dimensional network of electronic conductivity, forming a line contact with the active material, with low impedance and increased overall conductivity. Compared with traditional conductive materials, carbon nanotubes can further reduce the amount of conductive agent.

Multi-walled carbon nanotube MWCNT powder for resin:

There is a conductive masterbatch on the market with PP special resin as the base material and carbon nanotubes as the main conductive agent.

Studies have shown that in PC resin, adding only 2% of carbon nanotubes can achieve a surface resistivity of 10E+6Ω/SQ, while adding conductive carbon black and carbon fiber can increase the surface resistivity by 6-10% to achieve the same surface resistivity. One carbon nanotube can replace 3-5 conductive carbon black or carbon fibers.

In addition, adding carbon nanotubes to the resin can also enhance toughness and improve thermal conductivity.
