Why processing form matters for CNT additives

CNT performance is not determined only by nanotube quality, but also by how the material is introduced into the process.   SWCNT powders and SWCNT slurries behave very differently during mixing, dispersion, and storage, especially in battery electrode manufacturing.

SWCNT powder: challenges in real processing

Agglomeration and re-bundling

Dry SWCNT powders tend to agglomerate due to strong van der Waals forces.   High shear or long mixing times are required to redisperse them, often with inconsistent results.

Process variability

Small changes in mixing energy, order of addition, or solvent quality can lead to large variations in conductivity and viscosity when using powders.

SWCNT slurry: processing-stable conductive networks

Pre-dispersed and controlled

SWCNT slurry is pre-dispersed under controlled conditions, ensuring consistent nanotube separation and network formation before use.

Improved reproducibility

Compared with powders, slurries show better batch-to-batch consistency, more predictable rheology, and reduced risk of sedimentation or conductivity loss.

Why slurries are preferred in battery electrodes

Battery electrode manufacturing requires stable, repeatable slurry behavior.   SWCNT slurries reduce processing risk while enabling ultra-low loading conductive networks.
