Build conductive pathways
Individualized, high-aspect-ratio nanotubes can connect active particles across longer distances than conventional particulate conductive additives.
Carbon nanotubes for battery manufacturers
Carbon nanotubes for advanced batteries.
Industrial MOLECULAR REBAR® carbon nanotube dispersions and conductive additives engineered for lithium-ion and lead-acid battery manufacturing.
Why it matters
From bundled CNT powder to a usable conductive network
Carbon nanotubes (CNT) are high-aspect-ratio nanomaterials that can form long conductive and reinforcing pathways through battery active material. Raw CNT naturally forms difficult bundles, so BDS individualizes, protects, and disperses the nanotubes in application-ready formulations matched to the target chemistry and manufacturing process.
Review original performance data →Battery applications
What carbon nanotubes can do inside an electrode.
The useful result depends on CNT dispersion quality, loading, battery chemistry, and the surrounding formulation. BDS develops the material and validation plan around those variables.
Support faster charging
A well-integrated CNT network can reduce electrical limitations that restrict current flow at higher charging rates.
Reinforce active material
Nanotube networks can provide mechanical reinforcement through the electrode structure as the battery cycles.
Fit existing manufacturing
BDS supplies formulation and integration support for lithium-ion and lead-acid processes from development quantities through commercial formats.
Original BDS evidence
Evaluate the network—not just the raw nanotube.
BDS combines material processing, electrode imaging, cell testing, and manufacturer validation. Results remain chemistry-, formulation-, and test-specific.

Technical FAQ
Carbon nanotube questions.
Why use carbon nanotubes in battery electrodes?
High-aspect-ratio CNT can create conductive pathways and mechanical reinforcement through active material, supporting power, charging, and cycle-life goals.
How is a CNT dispersion different from dry powder?
A formulated dispersion addresses bundling, wetting, dosing, and integration so manufacturers can use CNT performance more consistently in their process while mitigating the safety concerns of raw CNT.
Which battery chemistries does BDS support?
BDS develops Molecular Rebar formulations for lithium-ion and lead-acid applications, with testing and integration support matched to the customer system.
Can BDS supply commercial volumes?
Yes. BDS supports 10 L jugs, 208 L drums, and 1,200 L totes for development through commercial-scale production.
