Description
Purified Single Walled Carbon Nanotubes 99.5%
This is a purified single walled carbon nanotube (SWCNT) powder with 99.5 wt% purity (+/- 0.5), a 1-2 nm outer diameter and a length over 100 um. The high aspect ratio and low defect density make it an effective conductive additive at low loading in lithium-ion, sodium-ion and solid-state battery electrodes, antistatic polymers, coatings, EMI shielding and structural composites. It is supplied as a black, low-bulk-density powder.

Applications
- Silicon and silicon-graphite anodes, sodium-ion electrodes, LFP cathodes and primer coatings for current collectors.
- General conductive additive for battery electrodes and coatings.
- Antistatic and ESD polymers, including colored and transparent parts.
- EMI shielding, structural composites and thermal management.
Representative data from the TDS: 2 wt% SWCNT in silicon, coin half-cell at 0.5C, retained over 92% capacity after 100 cycles with Coulombic efficiency near 99.95%. In polymers, percolation occurs at 0.05-0.2 wt% net SWCNT. Application results depend on formulation, equipment and process conditions; confirm with your own trials.
Dispersion and handling
Disperse by high-shear mixing, bead milling or probe sonication in NMP, water (with a dispersant) or resin carriers. Store sealed and dry at room temperature. Use local exhaust and respiratory protection with dry powder. See our dispersion guide and the safety data sheet.
