Lyten, the San Jose-based lithium-sulfur battery company, announced on March 20 that it will build its second Industrial Hub in Gdansk, Poland, centered on the former Northvolt BESS manufacturing facility it acquired last October. The move comes just weeks after the company established its first Industrial Hub at the old Northvolt Ett gigafactory in Skelleftea, Sweden. Together, the two hubs give Lyten control of more than 22 GWh of European battery manufacturing capacity and a clear path to commercializing lithium-sulfur chemistry at scale. The announcement caps a remarkable six-month acquisition spree. In that span, Lyten has absorbed nearly $5 billion worth of Northvolt assets, including cell production lines, BESS manufacturing equipment, R&D laboratories, and a battery recycling plant. What was once Europe's most celebrated battery startup now lives on as infrastructure for an American supermaterials company with very different technology. Lyten's Gdansk facility, formerly Northvolt Dwa, is Europe's largest BESS manufacturing plant with 6 GWh of annual capacity. From Northvolt's Collapse to Lyten's Expansion Northvolt's downfall sent shockwaves through the European battery industry. The Swedish company had raised over $15 billion in debt and equity, built partnerships with Volkswagen and BMW, and positioned itself as Europe's answer to CATL and LG Energy Solution. But persistent production problems, quality issues, and cash flow pressures forced the company into bankruptcy proceedings in late 2024. Lyten moved quickly. In July 2025, it agreed to acquire Northvolt Dwa, the 25,000-square-meter BESS manufacturing and R&D facility in Gdansk. The deal closed on October 16, 2025, and Lyten restarted operations almost immediately, resuming production of lithium-ion NMC-based Voltpack Mobile System (VMS) units for commercial, industrial, and data center customers. Sales were back on track before the end of 2025. Lyten restarted battery storage module production at the Gdansk plant within weeks of closing the acquisition in October 2025. The bigger prize came in February 2026, when Lyten completed the acquisition of Northvolt's Swedish assets for close to $5 billion. That deal included the Northvolt Ett gigafactory in Skelleftea, which has 16 GWh of cell production capacity, and Northvolt Labs, the company's R&D center in Vasteras. Lyten immediately declared Skelleftea the site of its first Industrial Hub, pairing the battery factory with a 1 GW AI data center campus being built by EdgeConneX. The company projects the Swedish hub will attract over $10 billion in additional infrastructure investment once it reaches full capacity. The Gdansk Hub: BESS Manufacturing Meets AI Infrastructure The Gdansk facility already holds a significant position. At 6 GWh of annual BESS production capacity, expandable to 12 GWh, it is the largest energy storage system manufacturing plant in Europe. Its production lines use state-of-the-art robotic automation to build modular, AI-enabled power management systems that can orchestrate power from solar, wind, generator, battery, and grid sources with millisecond response times. Under the Industrial Hub model, Lyten plans to combine this manufacturing capability with digital AI infrastructure, mirroring the approach in Sweden. The specifics will depend on a feasibility study Lyten expects to complete by the end of 2026. The study will assess local manufacturing requirements for Lyten's broader product portfolio, potential public-private partnerships, and the energy and utility infrastructure needed to support the expanded operation. Lyten's Industrial Hub model pairs battery manufacturing with data center campuses to create jobs and attract capital in a single location. "We are entering a new era of infrastructure development to support the multi-decade growth in power demand, AI data centers, and defense spending," CEO Dan Cook said at the Gdansk announcement event. "Poland has the right talent, the right infrastructure, and the right appetite for public-private partnerships to enable a Lyten Industrial Hub to thrive." The event drew senior Polish officials, including Finance and Economy Minister Andrzej Domanski and the Deputy Mayor of Gdansk, Piotr Grzelak. That level of political engagement signals Poland's interest in anchoring advanced manufacturing jobs as battery and AI investment floods into Europe. The Lithium-Sulfur Transition Lyten's near-term revenue comes from lithium-ion products. The Gdansk plant currently builds NMC-based BESS systems, and beginning in the second half of 2026, it will receive lithium-ion cells from the restarted Swedish gigafactory. But the long-term strategy centers on lithium-sulfur (Li-S) chemistry, which Lyten has been developing since its founding in 2015. Lyten manufactures lithium-sulfur cells at its San Jose headquarters for defense and autonomous systems customers, with plans to scale the technology across its European hubs. Li-S batteries use sulfur as the cathode material instead of the nickel, cobalt, or manganese compounds found in conventional lithium-ion cells. Sulfur is abundant, cheap, and mined worldwide, which eliminates the geopolitical supply chain risks that plague cobalt (concentrated in the Democratic Republic of Congo) and nickel (dominated by Indonesia and Russia). The theoretical energy density of Li-S cells is roughly five times higher than current lithium-ion technology, though practical cells today deliver about twice the energy per kilogram. Lyten's approach uses its proprietary 3D Graphene platform to stabilize the sulfur cathode and manage the "polysulfide shuttle" problem that has historically limited Li-S cycle life. The company currently manufactures Li-S cells at its San Jose headquarters for customers in the drone, autonomous systems, and defense sectors. The Northvolt Labs facility in Vasteras will now handle the work of scaling that chemistry to gigafactory volumes. At the Gdansk hub, Lyten plans to evaluate Li-S batteries for high-energy applications including drones, robots, and satellites. If the feasibility study supports it, the facility could transition from purely Li-ion BESS production to a mixed portfolio that includes Li-S products, potentially by 2027 or 2028. Building a European Battery Empire The scale of Lyten's European operation is now difficult to ignore. Between Sweden and Poland, the company controls roughly 22 GWh of operational or near-operational capacity for cells and BESS systems. A third Northvolt site in Heide, Germany, with 15 GWh of capacity, is still under construction and part of the acquisition portfolio. On March 13, Lyten also agreed to acquire Northvolt Revolt, a battery recycling plant, to support closed-loop material recovery at the Swedish hub. Taken together, these assets make Lyten one of the largest battery manufacturers in Europe by installed capacity, despite being a company that most people still associate with laboratory-stage lithium-sulfur research. The Northvolt acquisition transformed Lyten from a deep-tech startup with 550 patents and $625 million in equity funding into an operational industrial company with factories across three countries. Robert Chryc-Gawrychowski, CEO of Lyten Poland, framed the dual-purpose hub model as an answer to a fundamental tension in industrial policy. "Manufacturing creates much-needed jobs, but requires significant capital investment," he said. "AI data centers bring in huge investment and capital, but do not drive significant employment growth. By combining these two elements, we deliver the benefits of both and future-proof the local economy." What It Means for the Industry Lyten's rise on Northvolt's wreckage carries several implications for the broader battery sector. First, it demonstrates that the assets of failed battery startups retain enormous value when acquired by companies with viable technology and operational discipline. The factories, equipment, and trained wor
