Stellantis Invests in France's Tiamat, a Sodium-Ion Battery Technology Company

Stellantis Ventures, the corporate venture fund of Stellantis N.V., has invested in Tiamat, a France-based company that is developing and commercialising sodium-ion battery technology. Sodium-ion technology offers a lower cost per kilowatt-hour and is free of lithium and cobalt. 

Tiamat is a spin-off of the French National Centre for Scientific Research (CNRS).

The company will use proceeds from the fundraising round that includes Stellantis Ventures to launch construction of a sodium-ion battery plant in France for power tools and stationary storage applications first, and then targeting to scale-up production of products for battery electric vehicle (BEV) applications.

Stellantis has secured supplies of EV raw materials through 2027 by signing key agreements around the world.

It is also investing in the development of alternative technologies for energy storage, including solid-state batteries with Factorial Energy, lithium-sulfur chemistry with Lyten Inc. and sodium-ion with Tiamat.

Ned Curic, Stellantis Chief Engineering and Technology Officer, says: “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. 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.”

Established with an initial investment of €300 million, Stellantis Ventures targets early and later-stage startup companies that are developing cutting-edge technologies for the automotive and mobility sector.
