Stellantis Ventures has made a strategic investment in France-based sodium-ion battery developer Tiamat.

Tiamat says its sodium-ion technology is lithium- and cobalt-free and cheaper per kilowatt hour (kWh) when compared with lithium-ion batteries. The wide availability of sodium boosts sustainability and material sovereignty. 

Tiamat will use the new funding to start construction of a sodium-ion battery plant in France for power tools and stationary storage applications. In the future, the company plans to scale up production of second-generation products for EV applications.

Stellantis’s Dare Forward 2030 strategic plan calls for the company to reach 100% passenger car EV sales in Europe and 50% passenger car and light-duty truck EV sales in the US by 2030. The company will need to secure about 400 GWh of battery capacity to meet its sales expectations. Stellantis has also invested in solid-state batteries with Factorial Energy, and lithium-sulfur chemistry with Lyten.

“Exploring new options for more sustainable and affordable batteries that use widely available raw materials is a key part of the Dare Forward 2030 strategic plan,” 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.”
