The corporate venture fund of Stellantis N.V., Stellantis Ventures, has announced its position as a strategic investor in Tiamat, a France-based company that is developing and commercializing sodium-ion battery technology.
Sodium-ion technology reportedly offers a lower cost per kilowatt-hour and is free of lithium and cobalt; as it is abundantly available sodium offers benefits in increased sustainability and material sovereignty.
Honored with a Stellantis Ventures Award in 2023, Tiamat claims it is one of the first companies in the world to have commercialized sodium-ion technology in an electrified product.
“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, which will see us reach carbon net zero by 2038,” said Ned Curic, Stellantis chief engineering and technology officer.
“Our customers are asking for emissions-free vehicles that offer a combination of robust driving range, performance and affordability.”
To aid the development of these technologies, Stellantis has secured supplies of EV raw materials until 2027 by signing agreements for alternative technologies for energy storage, including solid-state batteries with Factorial Energy, lithium-sulfur chemistry with Lyten Inc. and sodium-ion with Tiamat.
Tiamat claims that it plans to use proceeds from Stellantis Ventures to launch construction of a sodium-ion battery plant in France for power tools and stationary storage applications, and to later scale-up production of second-generation products for BEV applications.
