OCSiAl has been appointed as a supplier to PowerCo, Volkswagen Group’s battery manufacturing subsidiary, for the Unified Cell battery platform at its Salzgitter facility, providing single wall carbon nanotubes for use in graphite anodes. The deal extends OCSiAl’s European footprint and supports local sourcing of critical battery materials across the continent.

Nanotubes will be supplied from OCSiAl’s Serbia production facility, which has completed audits conducted by PowerCo and other European and Asian battery manufacturers. The company reports that its TUBALL nanotubes are already deployed across the majority of European electric vehicle (EV) battery manufacturers, used in cathode and anode systems to improve energy density, fast-charging performance and cell cycle life.

OCSiAl announced a US$300m nanotube manufacturing facility in Luxembourg in November 2025 and continues to evaluate further European capacity to meet long-term demand.

In a statement, Gregory Gurevich, Senior Vice-President at OCSiAl, said: “Today, batteries containing OCSiAl nanotubes power around one million electric vehicles worldwide. In the PowerCo project, we supply nanotube solutions for graphite anodes. Single wall carbon nanotubes significantly enhance the electrical conductivity of graphite anodes and improve heat dissipation, enabling battery cells to operate at higher charging and discharging currents without overheating. These advanced conductive additives are essential for high-performance battery platforms produced at industrial scale.”
