Silicon Valley battery startup Lyten has completed its acquisition of Northvolt's business operations in Sweden, marking one of the most dramatic reversals in European battery manufacturing history. The deal gives Lyten control of the Northvolt Ett gigafactory in Skellefteå, along with R&D laboratories in Västerås. But Lyten isn't just picking up where Northvolt left off. The company announced plans to transform the Skellefteå site into a sprawling industrial hub that includes co-located AI data centers, with a potential campus scaling to 1 gigawatt . Data center developer EdgeConneX has already signaled intent to acquire a site at the hub. AI-generated image Inside a modern battery gigafactory production hall. From Bankruptcy to New Ownership Northvolt's collapse was one of the most closely watched stories in the battery industry throughout 2024 and into 2025. The Swedish company, once hailed as Europe's best hope for a homegrown battery champion, struggled with production ramp-up challenges, weakening EV demand forecasts, and fierce competition from Chinese manufacturers like CATL and BYD. The company filed for bankruptcy protection after burning through billions in funding. Its flagship Ett factory in northern Sweden never reached full production capacity, and plans for additional European gigafactories were shelved one by one. Lyten, which specializes in lithium-sulfur (Li-S) battery technology , had already acquired Northvolt's BESS production facility in Poland (Northvolt Dwa) before completing the Swedish deal. The combined footprint gives Lyten a significant European manufacturing base overnight, something that would have taken years and billions of dollars to build from scratch. Key Deal Terms Lyten is funding the acquisitions through equity investments and EdgeConneX's capital commitment to the data center campus. The company is also pursuing the acquisition of Northvolt's operations in Germany, though that deal has not yet closed. NMC Cells for Energy Storage, Li-S for the Future Lyten's immediate plan for Northvolt Ett is practical: get the factory producing and selling nickel manganese cobalt (NMC) cells on a commercial basis. Those cells will ship to the Northvolt Dwa facility in Poland for integration into battery energy storage systems (BESS). Commercial shipments are expected to begin in the second half of 2026.

Northvolt's R&D labs in Västerås, located about 100 kilometers from Stockholm, will continue NMC cell development while collaborating with Lyten's Silicon Valley team to scale up Li-S production. Lithium-sulfur batteries offer a theoretical energy density roughly double that of conventional lithium-ion cells, with the added benefit of avoiding cobalt and nickel entirely. Scaling lithium-sulfur cells to commercial production has proven difficult for the entire industry. Cycle life and sulfur cathode degradation remain persistent challenges. But Lyten's approach of pairing near-term NMC revenue with long-term Li-S development provides a financial bridge that pure-play Li-S startups typically lack. 1 GW Data Center Campus Potential 600+ Potential New Hires (12 months) H2 2026 First Commercial NMC Shipments The Data Center Play: Batteries as Infrastructure Lyten's decision to co-locate data centers at the Skellefteå site reflects a trend that has accelerated rapidly over the past year. AI training and inference workloads are driving unprecedented demand for reliable, high-capacity power. Battery storage is becoming a core infrastructure component for data centers, not an optional add-on. AI-generated image Data centers increasingly rely on co-located battery storage and renewable energy to meet 24/7 power demands. The Skellefteå location offers a specific advantage: proximity to substantial hydroelectric generation capacity in northern Sweden. Pairing hydro power with on-site battery storage could provide the kind of clean, firm power supply that hyperscale data center operators require for sustainability commitments. Lyten is not alone in pursuing this convergence. Earlier this week, energy-storage.news reported that utility Xcel Energy plans to install 30 GWh of iron-air batteries from Form Energy at a Google data center in Pine Island, Minnesota. Swiss data center operator NTS Colocation also announced a partnership with iron-sodium battery manufacturer Inlyte Energy to deploy 2 MW of storage capacity by 2028. Battery-Data Center Deals in 2026 • Lyten / EdgeConneX: 1 GW campus at former Northvolt site in Skellefteå, Sweden. Li-ion and Li-S storage. • Form Energy / Xcel / Google: 30 GWh iron-air installation at Pine Island, Minnesota data center. • Inlyte Energy / NTS Colocation: 2 MW iron-sodium pilot at Swiss data center, targeting 2028. What Northvolt's Second Life Means for Europe For Sweden and the EU, the Lyten acquisition is a mixed result. On one hand, the Northvolt Ett factory will keep operating and potentially expand, preserving manufacturing jobs and industrial capacity in a region that invested heavily in becoming a battery production hub. Lyten has committed to a rehiring program, working with local unions in both Västerås and Skellefteå, with the potential to bring on over 600 new employees within the next year. AI-generated image The Skellefteå region in northern Sweden has become a focal point for battery and industrial development. On the other hand, European ownership of the continent's most prominent battery factory has now passed to a US company. The strategic implications are hard to ignore as the EU continues pushing for domestic supply chain sovereignty through the EU Batteries Regulation and related industrial policy. The broader lesson from Northvolt's rise and fall is straightforward. Building cell manufacturing capacity from scratch is extraordinarily difficult and capital-intensive. Chinese manufacturers had a decade-long head start and continue to dominate on cost and scale. European and American players need either deep pockets and patience, or (as Lyten is demonstrating) a willingness to acquire distressed assets and repurpose them with a different business model. Looking Ahead: A New Model for Battery Companies Lyten's playbook is unusual in the battery industry. Rather than raising billions to build greenfield factories, the company is assembling a manufacturing network from Northvolt's remains while simultaneously developing next-generation lithium-sulfur chemistry. The data center campus adds a revenue diversification angle that most pure-play battery makers lack. Whether the strategy works depends on execution. The NMC production line at Northvolt Ett needs to reach consistent output quality. The lithium-sulfur program needs to clear its remaining technical hurdles. The data center campus needs tenants and grid connections. Each of these is a substantial challenge on its own. The Bottom Line: Lyten's acquisition of Northvolt's Swedish operations gives the US startup an instant European manufacturing base, a pipeline of NMC cells for the growing BESS market, and a platform for lithium-sulfur R&D. The addition of a 1GW data center campus signals that batteries and computing infrastructure are becoming inseparable. For the battery industry, the message is clear: the companies that survive the next decade may not be the ones that build the biggest factories, but the ones that find the smartest ways to combine storage with the industries that need it most.
