Carbon nanotubes can generally be divided into single-walled carbon nanotubes (SWCNT), double-walled carbon nanotubes (DWCNT), multi-walled carbon nanotubes (MWCNT), and few-walled carbon nanotubes (FWCNT).
Introduction to carbon nanotubes as conductive agents:
Carbon nanotube conductive slurry replaces traditional conductive agents to improve their energy density, fast charging and discharging, cycle life and other properties.
Compared with traditional conductive agents, carbon nanotubes have a unique hexagonal structure, excellent electrical conductivity, thermal conductivity, acid resistance and oxidation resistance.
The impedance of carbon nanotubes is only about 1/2 of that of carbon black. Low impedance can improve polarization and better cycle performance. In addition, according to industry insiders, the addition amount of traditional carbon black conductive agent is about 3% of the weight of the positive electrode material, while the addition amount of new conductive agents such as carbon nanotubes and graphene is reduced to 0.8%-1.5%. Low addition can save space and increase energy density.
Advantages of using carbon nanotube conductive agents:
Simple structure and stable chemical properties.
Small amount of addition, excellent conductivity.
Good elasticity, high mechanical properties.
