Introduction
Single-walled carbon nanotubes (SWCNTs) are seamless, nanometre-scale tubes formed when one or several graphene sheets roll around a central axis at a defined helical angle. Thanks to exceptionally low levels of amorphous carbon, metal residues and structural defects, they deliver outstanding electrical performance.

Product Parameter
Product feature
PRODUCT OVERVIEW Main Uses Conductive agents · Energy-storage devices · Semiconductor components 4.2 • Mass-producible continuous synthesis • High purity (carbon > 98 %) • High conductivity (high crystallinity & aspect ratio)
Application area
Applications • New-energy vehicles (battery additives & current collectors) • 3C electronics & flexible devices • Semiconductor interconnects • Power-grid infrastructure • Catalysis: SWCNTs act as catalysts or catalyst supports, boosting activity in heterogeneous and electrocatalytic processes. SWCNT Advantages in Cathodes Higher energy density Higher active percentage Can achieve higher compression density Reduce PVDF usage Improved processing Shorter mixing time (no need to premix with carbon black) Better adhesion Can achieve better performance at high rates May achieve extremely high rate performance LCO Cathode Example; SEM Electrode samples containing 0.06% SWCN show good particle surface coverage
