Today Stellantis Ventures, the corporate venture fund of Stellantis N.V., announced strategic investment in Tiamat, a France-based company developing and commercialising 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.
Tiamat is a spin-off of the French National Centre for Scientific Research (CNRS).
It was among 11 top-performing technology start-ups honoured with a Stellantis Ventures Award in 2023. It is the first company in the world to have recently commercialised a sodium-ion technology in an electrified product.
Sodium-ion technology promises a more cost-effective energy storage than today’s widely used lithium-ion battery technology.
According to Ned Curic, Stellantis Chief Engineering and Technology Officer:
“Our customers are asking for emissions-free vehicles with a 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.”
Stellantis is investing in the development of alternative technologies for energy storage, including solid-state batteries with Factorial Energy, lithium-sulphur chemistry with Lyten Inc. and sodium-ion with Tiamat.
Tiamat will use proceeds from the fundraising round, including Stellantis Ventures, to launch the construction of a sodium-ion battery plant in France for power tools and stationary storage applications.
Then Taiamat will scale up the production of second-generation products for BEV applications.
