OCSiAl has been selected to supply single wall carbon nanotubes for PowerCo’s Unified Cell battery platform. The agreement will see OCSiAl’s advanced nanotube solutions integrated into graphite anodes, enhancing charge performance and service life while improving overall cell safety. PowerCo is the battery manufacturing subsidiary of a major global automaker, and its Unified Cell design aims to standardize production across multiple vehicle models.
According to Gregory Gurevich, Senior Vice President at OCSiAl, single wall carbon nanotubes boost the electrical conductivity of graphite anodes and facilitate more effective heat dissipation. This combination allows cells to operate at higher charge and discharge rates without overheating. “These conductive additives are critical for achieving high-performance battery platforms at industrial scale,” he said, noting that batteries containing OCSiAl nanotubes already power around one million electric vehicles worldwide.
The nanotubes destined for PowerCo’s Salzgitter facility in Germany will originate from OCSiAl’s production site in Serbia. This arrangement supports European sourcing of essential battery materials and reinforces the region’s supply chain resilience. OCSiAl’s Serbian plant has met strict quality and reliability standards, successfully passing audits conducted by PowerCo and other leading European and Asian battery manufacturers.
OCSiAl’s TUBALL brand nanotubes are broadly used by European electric vehicle battery producers in both cathode and anode systems. They contribute to higher energy density, faster charging capabilities, and improved cycle life. With next-generation EV platforms driving increased demand, OCSiAl is evaluating further capacity expansion in Europe to meet long-term industry needs.
In November 2025, OCSiAl announced a $300 million investment in a flagship graphene nanotube facility in Luxembourg, positioning Europe at the forefront of advanced materials innovation. The new supply agreement with PowerCo marks another step in expanding the company’s presence in the European EV battery-cell supply chain.
