EV Battery Production Signals Market Divergence
LG Energy Solution's Canadian gigafactory has produced its one-millionth battery cell, marking a milestone in North American EV battery automation. In contrast, Stellantis has paused or sold battery plant projects due to weaker-than-expected EV demand. The diverging strategies highlight growing uncertainty and consolidation in the global battery supply chain.
- The NextStar Energy plant in Windsor, a joint venture originally between LG Energy Solution and Stellantis, is Canada's first large-scale EV battery factory with a planned annual capacity of over 45 gigawatt-hours. LG Energy Solution is now set to take full ownership after Stellantis sold its 49% stake, a move intended to allow the plant to pursue third-party business and scale at an accelerated rate. - Stellantis's pullback is part of a broader strategic reset, including a €22.2 billion charge in late 2025, due to what CEO Antonio Filosa called an "overestimation of the pace of the energy transition." The company is now resetting its EV supply chain to better reflect customer demand and shifting regulations. - The Automotive Cells Company (ACC), a joint venture including Stellantis, has permanently abandoned plans for battery gigafactories in Kaiserslautern, Germany, and Termoli, Italy. This decision follows a pause initiated eight months prior due to high costs, strategic challenges, and slowing EV demand. - Beyond market demand, a key reason for the European plant cancellations was the need to re-evaluate battery chemistry. The initial focus on Nickel-Manganese-Cobalt (NMC) batteries is shifting toward lower-cost Lithium Iron Phosphate (LFP) technology, necessitating a strategic partnership with LFP leader CATL. - The now-abandoned Italian plant in Termoli was a key project in the country's transformation of traditional combustion engine facilities. The Italian government had withdrawn its funding commitment in September 2024 after ACC failed to reaffirm its plans for the site. - Artificial intelligence and machine learning are being integrated into battery manufacturing to accelerate development and improve quality control. AI algorithms can rapidly detect process anomalies, predict battery behavior under stress, and shorten the discovery timeline for new materials. - The Windsor NextStar plant will now pivot to serve a more diverse customer base beyond Stellantis, targeting the growing energy storage system (ESS) industry. This shift aligns with LG Energy Solution's goal to increase its global ESS production capacity to over 60 GWh. - The global lithium-ion battery market is projected to grow from approximately $105 billion in 2021 to $174 billion by 2026. Price disparities are significant, with battery packs in China being 30-35% cheaper than in the United States and Europe in 2025.
