Details

This water-based dispersion of single-walled carbon nanotubes (SWCNTs), developed by Tuball under model MA-EN-CO-0010, is formulated as a conductive additive for lithium-ion battery electrodes. Containing 0.4 wt% SWCNTs, 99.0 wt% water, and 0.6 wt% dispersant, the dispersion exhibits non-Newtonian fluid behavior with pseudoplastic and thixotropic properties—viscosity changes with both shear rate and shear time, enabling efficient processing and uniform distribution in electrode slurries. The product is designed for use in high-performance battery manufacturing, where it enhances electronic conductivity and mechanical integrity of electrode films. It has a shelf life of one year when stored sealed at room temperature, and is available in 500 g and 1000 g packaging sizes.

A dispersion of single-walled carbon nanotubes (SWCNTs) in water is used as a conductive additive in lithium-ion batteries.

Ingredients:

Single-walled carbon nanotubes 0.4wt.%
Water 99.0wt.%
Dispersant 0.6wt.%

Non-Newtonian fluids, single-walled carbon nanotubes (SWCNTs) exhibit both pseudoplasticity and thixotropy, meaning their viscosity depends on the shear rate (pseudoplasticity) and the shear time (thixotropy). The thixotropic properties of SWCNTs are complex, transitioning between thixotropic and rheotropic behavior under specific conditions.
