Stellantis Ventures, the corporate venture fund of Stellantis N.V., has unveiled its strategic investment in Tiamat, a cutting-edge France-based firm at the forefront of sodium-ion battery technology development and commercialization. The move aligns with Stellantis’ commitment to providing clean, safe, and affordable mobility, as articulated in their ambitious Dare Forward 2030 strategic plan.

Sodium-ion technology, championed by Tiamat, emerges as a game-changer, offering a lower cost per kilowatt-hour and freedom from lithium and cobalt. Abundant sodium not only enhances sustainability but also ensures material sovereignty, marking a significant step towards a greener future.

Tiamat, recognized among the top-performing technology start-ups with a Stellantis Ventures Award in 2023, has achieved a groundbreaking milestone by being the first company globally to commercialize sodium-ion technology in an electrified product.

Ned Curic, Stellantis Chief Engineering and Technology Officer, emphasizes the importance of this investment, stating, “Exploring new options for more sustainable and affordable batteries that use widely available raw materials is a key part of our ambitions of the Dare Forward 2030 strategic plan that will see us reach carbon net zero by 2038.” He adds, “Our customers are asking for emissions-free vehicles that offer a combination of robust driving range, performance and affordability. This is our North Star, as Stellantis and its partners work today to develop ground-breaking technologies for the future.”

The Dare Forward 2030 strategic plan sets forth Stellantis’ commitment to electric propulsion, aiming for a 100% passenger car battery electric vehicle (BEV) sales mix in Europe and a 50% mix in the United States by 2030. To achieve these goals, Stellantis is securing approximately 400 GWh of battery capacity, positioning the company on a trajectory to become a carbon net-zero corporation by 2038.

In supporting this ambitious agenda, Stellantis has secured supplies of Electric Vehicle (EV) raw materials through 2027 and invested in alternative energy storage technologies, including solid-state batteries with Factorial Energy, lithium-sulfur chemistry with Lyten Inc., and sodium-ion with Tiamat.

Tiamat, a spin-off of the French National Centre for Scientific Research (CNRS), stands poised to leverage its innovations further. The proceeds from the fundraising round, including Stellantis Ventures’ investment, will be utilized by Tiamat to initiate the construction of a sodium-ion battery plant in France. The initial focus will be on power tools and stationary storage applications, followed by scaling up production for second-generation products tailored for Battery Electric Vehicle (BEV) applications.

Stellantis Ventures’ strategic investment in Tiamat positions both entities at the forefront of sustainable mobility, contributing to a future where emissions-free vehicles seamlessly blend robust driving range, performance, and affordability.
