Stellantis Ventures, the investment arm of Stellantis N.V., has announced its strategic investment in Tiamat, a French company focusing on sodium-ion battery technology.

Sodium-ion tech, which is both cost-effective and devoid of lithium and cobalt, harnesses abundant sodium for enhanced sustainability and material independence.

Tiamat, recognised as one of the top-performing startups with a Stellantis Ventures Award in 2023, recently achieved a milestone by commercialising sodium-ion technology in an electrified product.

This investment aligns with Stellantis' commitment to providing clean, safe, and affordable mobility globally. Sodium-ion technology holds promise for more economical energy storage compared to the prevalent lithium-ion batteries.

Ned Curic, Stellantis Chief Engineering and Technology Officer stressed the importance of exploring sustainable and cost-effective battery options as part of their Dare Forward 2030 plan, aiming for carbon neutrality by 2038.

The plan focuses on electric propulsion, targeting a 100% passenger car battery electric vehicle (BEV) sales mix in Europe and a 50% mix in the U.S. by 2030. Stellantis is actively securing 400 GWh of battery capacity to meet these targets and is on track to achieve carbon neutrality by 2038.

Stellantis is committed to sustainable practices, securing EV raw materials through 2027 and investing in alternative energy storage technologies, such as solid-state batteries, lithium-sulfur chemistry, and sodium-ion technology.

Tiamat, a spin-off of the French National Centre for Scientific Research (CNRS), plans to use the investment to build a sodium-ion battery plant in France, initially focusing on power tools and stationary storage applications before scaling up for BEV applications.
