Inside GM's Transformation of EV Battery Production

Batteries, once limited to powering devices like camcorders, have transformed into the lifeline of modern electric vehicles, capable of propelling trucks over extensive distances on a solitary charge.

General Motors (GM) is at the forefront of this evolution, not merely adapting to it but actively refining the very processes that underpin EV battery production.

GM's current ambition revolves around aligning advancements in lithium-ion battery technology with manufacturing efficiency, localised sourcing and cost-effectiveness. This approach focuses on manufacturing these critical components more efficiently, rapidly and geographically closer to their primary consumer markets.

Such a methodology is essential in today's competitive global landscape, where agility, resilience and mastery over supply chains are indispensable.

Central to GM's battery strategy is the expansion of its production capabilities, facilitated through strategic partnerships. Its venture with LG Energy Solution, known as Ultium Cells, has propelled the company to become the largest original equipment manufacturer (OEM) battery cell producer across North America.

This leading position is a testament to its focus on quality, production volume and consistency—crucial factors in standing against the world's top battery manufacturers.

Through strategic investments, GM has become the second-largest seller of EVs in the United States. In 2025, the company experienced a 94% surge in its first-quarter EV sales.

GM offers a diverse array of 12 electric models, providing a broad spectrum of choices for consumers. "If there's one thing I've learned during my career, it's that sustainable business is smart business," states Cassandra Garber, the company's Chief Sustainability Officer.

"Reducing risk, seizing innovation and growth opportunities WHILE delivering real and meaningful impact is where it’s at. It’s hard, but when done, and done well, it’s transformative for both business and our world."

Looking towards the future, GM plans further expansion of its manufacturing might. In collaboration with Samsung SDI, it will launch a battery production facility in Indiana by 2027.

This joint venture will focus on producing prismatic cells, a design that enhances flexibility, allowing GM to tailor battery technology to match each vehicle model's distinct requirements.

Strengthening the battery supply chain

GM isn't solely focused on cell production; the company is actively expanding its supply chain. This effort involves securing critical materials such as lithium, manganese and nickel from North American sources, thus cementing local supply reliability.

Additionally, GM is replicating this localised approach to the manufacturing of vital battery components like cathodes, anodes, electrolytes and separators. Controlling these elements means enhanced stability, slashed transportation expenses and minimised disruptions.

By 2028, GM aims to revolutionise its battery supply chain by magnifying the North American content of its components eightfold, integrating sourcing, manufacturing and assembly processes across the continent.

According to Mary Barra, Chair and CEO of GM: "Sustainability is not just good policy. It’s good business—good for the company, for employees and for recruiting and retaining the best people, people who will help us achieve our vision."

This vision of regional integration offers numerous benefits, extending to end consumers. Implementing prismatic cells and transitioning to lithium iron phosphate (LFP) chemistry within models like the Chevrolet Silverado EV significantly trims down battery module parts by 75% and overall battery pack components by 50%, which translates into a cost reduction of US$6,000 per battery pack.

These savings ultimately lead to more competitively priced EVs, without compromising their range.

Innovation rooted in research

To maintain a leadership position in battery innovations, GM relies heavily on its Wallace Battery Cell Innovation Center (BCIC) located in Michigan.

The centre is devoted to developing advanced battery chemistries that promise heightened energy density at reduced costs, tackling two of the most pressing challenges in battery engineering.

Operating as an intermediary between research and mass production, BCIC accelerates the transition of experimental cells from lab trials to widespread manufacturing, thereby fostering more rapid innovation and greater agility across GM's EV lineup.

GM invests approximately US$7bn annually into research and development in the US, supporting both technological advancements and local employment, furthering its leadership in the automotive revolution and energy transformation.

By strategically investing in every stage of the battery process—from raw material acquisition to chemistry development and factory creation—GM is meticulously constructing a supply chain capable of supporting sustained American dominance in the evolving global EV marketplace.
