Carbon nanotube battery additives
A small amount of carbon nanotubes mixed into a battery's electrodes forms a network that carries current through the material, letting cells charge and discharge harder without overheating.

The rule
Widely used: in products or treatments that reach millions of people, or sold in ordinary shops.
- Batteries containing OCSiAl's nanotubes were powering about a million electric vehicles, and Volkswagen's battery company PowerCo picked OCSiAl as a supplier for its Unified Cell. electrive, 26 June 2026
The short version
What you need to know
- Is it really nano?
Truly nano
The additive is the nanotubes themselves.
electrive, 26 June 2026- Where you’ll find it
In electric car batteries: about a million EVs carry OCSiAl's nanotubes alone.
