Lyten is rebuilding Europe’s battery supply chain from the inside out. The San Jose, California-based advanced materials company—founded in 2015 by CEO Dan Cook—has spent the past 18 months methodically acquiring the manufacturing infrastructure that Northvolt left behind, executing one of the most consequential battery industry transactions in recent memory.
With nearly $5 billion in Northvolt asset book value now secured across Sweden, Poland, and California—and Germany in progress—Lyten has transformed from a well-funded U.S. deep-tech startup into a transatlantic battery manufacturer with existing gigafactory-scale infrastructure. The company’s proprietary LytCell™ lithium-sulfur battery technology, built on its Lyten 3D Graphene™ platform, sits at the center of a strategy that aims to produce cells free of nickel, cobalt, manganese, and graphite, while reviving thousands of European manufacturing jobs.
For investors, policymakers, and industry professionals watching China’s dominance of global battery supply chains, Lyten’s moves represent one of the clearest Western attempts to reclaim ground—using existing, already-built infrastructure rather than starting from scratch.

Company Background & Market Position
Lyten was incorporated in 2015 with a core thesis: that three-dimensional graphene could serve as a platform material to build fundamentally better products across multiple industries. Under CEO and co-founder Dan Cook, the company built its first semi-automated production line in San Jose, shipping pilot samples of its LytCell™ lithium-sulfur batteries to U.S. and European automakers beginning in May 2024.
The company’s investors reflect its cross-sector ambitions. Stellantis invested in 2023 to co-develop lithium-sulfur EV batteries and lightweighting solutions. FedEx, Honeywell, and the Defense Innovation Unit have also backed the company, signaling credibility across logistics, industrial systems, and national security applications.
Lyten positions itself not as a niche technology supplier, but as what it calls a “supermaterial applications company”—one whose graphene platform produces batteries, structural composites (LytR™), concrete admixtures (S Cure™), and sensors from a common materials foundation. With $625 million raised and 541 patents granted or pending, Lyten enters the gigafactory era with both deep IP and real manufacturing infrastructure.
Manufacturing Capacity & Infrastructure
Lyten’s manufacturing story is really two parallel narratives: a proven pilot operation in California and a rapid-scale acquisition strategy in Europe.
In the United States, Lyten’s 145,000 sq ft San Jose facility has produced cathode active materials (CAM), lithium-metal anodes, and assembled LytCell batteries since 2023, with automated line yields consistently above 90%. In April 2025, the company began U.S. production of battery-grade lithium-metal alloys and foils there. A second California site in San Leandro (the former Northvolt/Cuberg plant, acquired November 2024) is being retooled to reach up to 200 MWh of annual capacity.
In Europe, Lyten’s acquisition program has moved at considerable speed:
- Poland (October 2025): Acquisition of Northvolt Dwa in Gdańsk closed, restarting Europe’s largest BESS manufacturing facility at 6 GWh capacity, expandable to 10 GWh.
- Sweden (February 2026): Acquisition of Northvolt Ett (Skellefteå) and Northvolt Labs (Västerås) completed, bringing 16 GWh of operational battery manufacturing capacity into Lyten’s portfolio.
- Germany (in progress): Northvolt Drei in Heide—targeting up to 15 GWh and 1,000 jobs—is part of a binding agreement announced in August 2025.
- Recycling (Q2 2026 expected): A binding agreement for the Revolt battery recycling plant in Skellefteå was announced in March 2026, adding closed-loop capability to the Swedish industrial hub.
The long-term infrastructure target is more than 100 GWh of combined capacity across Europe and North America.
Technology & Product Portfolio
Lyten’s primary battery product, LytCell™, uses 3D Graphene’s “Sulfur Caging” architecture to address the polysulfide shuttle problem that has historically limited lithium-sulfur battery commercialization. Current prototypes demonstrate 250–325 Wh/kg, with a technology roadmap targeting 400 Wh/kg by 2026.
The performance case against conventional lithium-ion chemistries is direct:
- Up to 50% weight reduction compared to NMC cathodes; up to 75% compared to LFP
- 60% lower carbon footprint than leading lithium-ion batteries
- No nickel, cobalt, manganese, graphite, or iron-phosphorus in the cathode chemistry
- Demonstrated resistance to thermal runaway, with no more than 20°C temperature rise in nail penetration tests
- Operational temperature range: -20°C to 140°C
Cell formats include pouch and cylindrical (18650 and MLP), with NDAA-compliant cells produced for aerospace, defense, and drone applications.
Beyond batteries, Lyten’s 3D Graphene platform also powers:
- LytR™: Graphene-infused thermoplastic composites reducing plastic use by up to 50% and weight by half, with a 55% lower carbon footprint.
- S Cure™: A concrete admixture under active testing with two of the world’s five largest ready-mix concrete producers.
- 3D Printer Filament: Graphene-enhanced additive manufacturing filament enabling metal replacement.
- Structural Adhesive: High-strength bonding material launched at PRI 2025.
- IoT Sensors: High-sensitivity arrays for automotive, aerospace, industrial, and health applications.
Strategic Initiatives & Market Context
Lyten’s acquisition of Northvolt’s assets has landed squarely in the debate over European battery independence. The collapse of Northvolt—Europe’s most prominent homegrown battery champion—left a visible gap. Lyten’s entry into that gap, backed by North American and European equity investors and EdgeConneX (which is co-investing in a data center campus within Lyten’s Skellefteå industrial hub), positions the company as a direct answer to questions about Western supply chain resilience.
On labor, Lyten’s Swedish entities—Lyten Ett AB, Lyten Labs AB, and Lyten AB—have joined the Teknikarbetsgivarna employers’ association, binding them to collective agreements with IF Metall, Unionen, Sveriges Ingenjörer, and Ledarna. Former Northvolt employees receive priority rehiring rights under Swedish law, and Lyten plans to add more than 600 employees in Sweden within 12 months of closing.
In North America, Lyten sources industrial-grade sulfur from California-based suppliers, produces lithium-metal foil from U.S. alloys, and manufactures its cathodes and anodes domestically—a profile that aligns well with programs like the Inflation Reduction Act.
Future Outlook
Lyten enters 2026 as a company in genuine transition. The acquisition phase is substantially complete; the execution phase is now beginning. Commercial lithium-ion NMC cell production from Sweden is targeted for 2H 2026, with lithium-sulfur integration to follow as the technology scales through qualification.
The central question—whether Lyten can convert $5 billion in acquired infrastructure into a functioning, competitive battery manufacturer—remains open. Lithium-sulfur technology is still completing multi-year automotive qualification cycles, and cycle life, currently in the 250–500 range at useful depths of discharge, will need to improve further for mass-market EV adoption.
What Lyten has done, that very few Western battery companies have managed, is secure real manufacturing capacity without having to build it from the ground up. For stakeholders watching whether the West can build a viable alternative to Asian battery supply chains, Lyten’s next 18 months will be one of the more instructive data points in the industry.
