GM and LG Just Pivoted a U.S. Battery Plant — and It Signals a Bigger Shift Than Expected

General Motors and LG Energy Solution just made an unexpected move at their Tennessee battery facility, and it reveals how quickly the energy landscape is changing. The Ultium Cells joint venture is investing $70 million to retool its Spring Hill plant to produce lithium-iron phosphate batteries for energy storage systems instead of focusing solely on electric vehicles, bringing back 700 workers who were laid off earlier this year.

The shift comes at a time when EV demand has softened in the U.S., but energy storage is experiencing explosive growth. Grid-scale batteries are increasingly needed to stabilize power systems, support renewable energy, and meet the massive electricity demands of new data centers powering artificial intelligence.

This isn’t just about one factory changing what it makes. The pivot highlights how battery manufacturers are adapting to market realities while positioning themselves for long-term opportunities beyond passenger vehicles. What GM and LG are doing in Tennessee could signal where the broader battery industry is headed as companies balance EV ambitions with the booming demand for stationary energy storage.

GM and LG’s Major Shift: The Lansing Battery Plant Pivot

General Motors decided to exit its joint venture at the Lansing battery facility, transferring full ownership to LG Energy Solution in a deal valued at approximately $2 billion. The transaction dissolved the 50-50 partnership structure that had defined Ultium Cells LLC’s third North American plant.

Why GM Sold Its Lansing Stake to LG Energy Solution

General Motors backed away from the Lansing facility as part of a broader recalibration of its electric vehicle strategy. The automaker faced slower-than-expected EV adoption rates and needed to adjust its capital expenditure plan accordingly.

GM announced the non-binding agreement in late 2024, with plans to close in the first quarter of 2025. The move allowed General Motors to redirect resources toward its Orion Assembly plant, where it retained full control of Silverado EV production.

Paul Jacobson and other GM executives emphasized the company’s commitment to electrification despite the ownership change. The sale didn’t signal a retreat from EVs but rather a strategic shift in how GM allocated battery cell manufacturing investments across its operations.

Financial and Ownership Details of the Deal

LG Energy Solution acquired the GM stake for approximately $2.03 billion, with the transaction closing in May 2025. The purchase price reflected both the nearly completed 2.8-million-square-foot facility and installed equipment valued at over $600 million.

Key Financial Terms:

Purchase price: $2.03 billion (3.1354 trillion won)
Facility construction cost: $432.2 million
Equipment value: $608.1 million
State incentive transfer: $120 million

The Lansing plant became LG Energy Solution’s third standalone factory in North America. This ownership structure freed LG to pursue contracts beyond the Ultium Cells brand, including a notable Tesla deal worth $4.3 billion for battery cells made at the Michigan facility.

Impacts for Lansing and Ultium Cells Workforce

The ownership transition required Michigan to decouple its $600 million mega-subsidy deal between the two companies. LG Energy Solution received $120 million in transferred incentives and committed to hiring 1,360 workers at wages around $55,000 annually.

Both companies maintained their combined pledge of 3,200 new jobs despite the ownership split. GM became responsible for 1,840 positions at Orion Assembly, while LG Energy Solution took on the Lansing hiring obligations.

As of September 2024, only 148 jobs existed at the former Ultium facility. The workforce expansion depends on production ramp-up and securing customers beyond General Motors, which LG Energy Solution can now pursue as sole owner of the battery cell plant.

The Bigger Shift: Battery Innovation and the U.S. EV Market

The Spring Hill plant retooling reflects GM’s broader battery strategy that extends well beyond a single facility change. The company is diversifying its chemistry portfolio and production methods while competitors make similar moves to adapt to cost pressures and shifting market demands.

From Pouch to Prismatic: Evolving Battery Technology

Ultium Cells has primarily focused on pouch cells for EV applications, but the battery technology landscape is evolving rapidly. Pouch cells offer flexibility in packaging and design, making them popular for vehicles where space optimization matters.

Prismatic cells represent a different approach. They’re encased in rigid metal housings that provide structural benefits and improved thermal management. Contemporary Amperex Technology and other Asian manufacturers have dominated prismatic cell production, particularly for grid-scale applications where durability and longevity outweigh weight concerns.

GM and LG Energy Solution are now positioning their manufacturing platform to handle multiple cell formats. The Spring Hill facility’s shift to LFP production for energy storage demonstrates this flexibility, even as the company maintains its pouch cell operations at other locations for EV applications.

The Move Toward Lower-Cost LFP Batteries

Lithium iron phosphate batteries are becoming the preferred chemistry for energy storage projects due to their cost advantages. LFP cells cost significantly less to produce than the high-nickel NCMA batteries used in many EVs, making them ideal for stationary applications where weight isn’t a limiting factor.

LG Energy Solution plans to exceed 60 gigawatt-hours of global energy storage battery production capacity this year. More than 80% of that capacity will be located in North America, positioning the joint venture to serve the growing grid storage and data center markets.

The company is expanding its network to produce standard JF2 LFP pouch cells across facilities in Holland and Lansing, Michigan, Windsor, Ontario, and through its Honda joint venture. All of these sites are expected to produce LFP cells by the end of 2026.

Strategic Implications for GM’s EV Roadmap

GM consolidated its NCMA GEN1 battery cell production for electric vehicles at the Warren, Ohio facility as part of the Spring Hill transition. This consolidation allows the company to maintain EV battery output while redirecting Tennessee capacity toward the faster-growing energy storage sector.

Kurt Kelty from GM has indicated the company is exploring ways to extend battery expertise beyond transportation into grid-scale applications. The data center market represents a particularly compelling opportunity as AI infrastructure drives unprecedented electricity demand.

GM’s EV strategy continues to evolve alongside these production changes. The company achieved strong EV sales growth recently, though federal policy changes have created uncertainty around incentives that previously supported electric vehicle adoption.

Industry-Wide Impact: Competitors and the Changing Market

Samsung SDI and other battery manufacturers are making similar strategic adjustments as the market shifts. The battery industry is responding to two simultaneous trends: softer EV demand growth in certain segments and explosive energy storage requirements.

Contemporary Amperex Technology maintains its position as the global leader in battery production, but North American manufacturers are gaining ground through localized production and supply chain development. LG Energy Solution’s expansion strategy directly competes with Chinese manufacturers for the growing stationary storage market.

The industry is also advancing next-generation technologies including lithium manganese rich chemistries that could offer performance improvements at lower costs. These innovations are being developed in research facilities while current production focuses on scaling proven technologies like LFP for immediate market needs.
