Stellantis invests in sodium-ion battery developer Tiamat

Sodium-ion technology is a more cost-effective energy storage solution compared to today’s widely used lithium-ion battery technology.

Stellantis Ventures, the corporate venture fund of Stellantis N.V., said it will participate as a strategic investor in Tiamat, a France-based company that is developing and commercializing sodium-ion battery technology. Sodium-ion technology offers a lower cost per kilowatt-hour and is free of lithium and cobalt. Abundantly available sodium offers benefits in increased sustainability and material sovereignty, Stellantis Ventures said.

Sodium-ion technology holds the promise of more cost-effective energy storage compared with today’s widely used lithium-ion battery technology, the company said.

“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,” Ned Curic, Stellantis chief engineering and technology officer, said. “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.”

According to Stellantis, shifting to electric propulsion is a key pillar of its Dare Forward 2030 strategic plan. It includes reaching a 100% passenger car battery electric vehicle (BEV) sales mix in Europe and a 50% passenger car and light-duty truck BEV sales mix in the United States by 2030. To achieve these sales targets, Stellantis said it is securing approximately 400 GWh of battery capacity and is on track to become a carbon net zero corporation by 2038, all scopes included, with single-digit percentage compensation of remaining emissions.
