SWCNT Slurry for Battery Electrodes | Ultra-Low Loading Conductive Additive – Single-Walled Carbon Nanotube Dispersion f
Lower percolation threshold than carbon black and MWCNT. Stable dispersion for NMP / water-based slurries.
Introduction
SWCNT Slurry – High-Conductivity Single-Walled Carbon Nanotube Dispersion for ESD Plastics, Coatings and Battery Materials
SWCNT slurry is a high-conductivity, pre-dispersed formulation of single-walled carbon nanotubes. It provides fast, uniform dispersion in plastics, coatings and battery materials, enabling ultra-low loading, stable resistivity and clean processing in water, NMP or ethanol.
Introduction
Our SWCNT slurry is formulated using high-aspect-ratio single-walled carbon nanotubes (eDIPS process). Through proprietary dispersion technology, the CNT network remains stable and uniform in water, NMP, ethanol and mixed systems. It is designed for ESD plastics, conductive coatings, printed electronics and battery electrode additives.
Key Features
- Excellent dispersibility in water, NMP and ethanol
- Long-aspect-ratio SWCNTs preserved during dispersion
- 5–10× lower loading vs. carbon black for same resistivity
- Compatible with PC/ABS, PA, PBT, TPU, PU, epoxy and coatings
- Stable electrical performance and uniform percolation
- Available in multiple concentrations (0.05–0.4 wt%)
Applications
- ESD & antistatic plastics
- Conductive and shielding coatings
- Printed electronics and conductive inks
- Lithium-ion battery electrodes
- Transparent and semi-transparent conductive films
