November 28, 2025: Norwegian battery materials firm Vianode is set to supply US lithium tech venture C4V with high-performance synthetic anode graphite for BESS systems, under a letter of intent announced on November 25.

The companies are planning an offtake agreement through which Vianode would supply synthetic graphite to New York-based C4V and its gigafactory joint ventures through 2032, with first deliveries in the second half of 2026.

Under the collaboration, Vianode’s materials would be combined with C4V’s innovative cobalt- and nickel-free cathode technology.

The letter of intent marks Vianode’s first agreement in the BESS segment. Initial material supplies will be produced at the group’s ‘Via ONE’ graphite plant in Norway, followed by shipments from Via TWO — Vianode’s recently announced large-scale facility to be developed in Ontario.

The partners said their collaboration would develop a regional supply chain for synthetic anode graphite and critical battery materials, while eliminating US concerns of being dependent on so-called foreign entities of concern.

That is important as more than 95% of synthetic graphite used in lithium ion batteries for BESS and EVs is produced in Asia, which Vianode said creates significant import requirements in North American markets.

Glen Kozeli, director of sales and business development for the Americas at Vianode, said the partnership would also lay the foundation for exploring joint business opportunities globally.

A US clamp down on the use of content in batteries supplied by China and other players was unveiled by the former Biden administration in 2023.

Earlier this year, president Donald Trump signed an executive order instructing the US commerce department to analyze critical mineral supply chains and propose ways to ramp up domestic production while reducing reliance on imports.
