OCSiAl, a Luxembourg based manufacturer of single wall carbon nanotubes, has signed a supply deal with PowerCo, Volkswagen's battery subsidiary. The nanotubes will go from OCSiAl's Serbia plant to PowerCo's Salzgitter factory in Germany. They are used in graphite anodes to improve conductivity and heat dissipation, which allows faster charging and longer battery life. The deal supports local sourcing of critical battery materials within Europe. OCSiAl says its nanotubes are already in about one million EVs globally. The company is also building a USD 300 million graphene nanotube facility in Luxembourg. Demand is rising as automakers shift to next generation battery platforms like PowerCo's Unified Cell. The article does not disclose the volume or value of the supply agreement, but it signals growing European supply chain integration for battery materials.

This is a supply chain story for EV batteries. OCSiAl ships nanotubes from Serbia to PowerCo in Germany. The material improves anode conductivity and heat dissipation. No volume or value disclosed, but it shows Europe trying to build local battery material sourcing.

The local sourcing angle is the main takeaway here. Serbia to Germany is still a short haul compared to shipping from Asia. But I wonder how much of the raw material for those nanotubes comes from outside Europe.

Good point. OCSiAl's Serbia plant is relatively new. The Luxembourg facility is still under development. If the precursor materials come from China, the local sourcing claim gets weaker. Still, having nanotube production inside Europe is a step forward for battery supply chains.

This fits the EU's Critical Raw Materials Act narrative. The question is whether these nanotubes qualify as strategic under that framework. Also, PowerCo is getting supply from two nanotube suppliers now. Cabot signed a deal earlier this year. Diversification is happening.

Nanotubes in anodes are a niche but important improvement. Better conductivity means less carbon additive needed, which can boost energy density. For EVs that translates to either longer range or smaller packs. The heat dissipation part is key for fast charging without degradation.
