Stellantis N.V. and Zeta Energy Corp. have announced a joint development agreement to advance battery cell technology for electric vehicle (EV) applications. The partnership focuses on lithium-sulfur EV batteries,
designed to achieve enhanced gravimetric energy density while maintaining volumetric energy density comparable to today’s lithium-ion batteries.
Roadmap to Production
The collaboration will concentrate on pre-production development and planning, with a goal of deploying lithium-sulfur batteries in Stellantis EVs by 2030. These batteries are expected to provide significantly lighter battery packs with the same usable energy, enabling improved range, handling, and overall performance.
The technology also has the potential to , with , enhancing convenience for EV owners. With projected costs less than half that of current lithium-ion batteries on a per kilowatt-hour basis, this innovation addresses critical challenges in cost and scalability, facilitating broader EV adoption.
Advancing EV Battery Technology
Lithium-sulfur battery technology offers enhanced performance at a lower cost compared to conventional lithium-ion batteries. Widely available and cost-effective sulfur reduces production expenses and minimizes supply-chain risk.
“Our collaboration with Zeta Energy is another step in helping advance our electrification strategy as we work to deliver clean, safe and affordable vehicles,” said Ned Curic, Stellantis Chief Engineering and Technology Officer. “Groundbreaking battery technologies like lithium-sulfur can support Stellantis’ commitment to carbon neutrality by 2038 while ensuring our customers enjoy optimal range, performance and affordability.”
Zeta Energy’s lithium-sulfur batteries utilize sustainable materials, including waste products, methane, and unrefined sulfur. This approach significantly lowers CO2 emissions compared to existing technologies and eliminates the need for critical materials like cobalt, graphite, manganese, and nickel, addressing both environmental and supply chain challenges.
Sustainable Manufacturing and Supply Chain
The batteries incorporate Zeta Energy’s proprietary sulfurized carbon cathodes and 3D metallic lithium anodes. By using unrefined sulfur, a byproduct of various industries, these batteries align with Stellantis’ Dare Forward 2030 strategic plan, which includes the release of over 75 battery electric vehicle (BEV) models by the end of the decade.
“We are very excited to be working with Stellantis on this project,” said Tom Pilette, CEO of Zeta Energy. “The combination of Zeta Energy’s lithium-sulfur battery technology with Stellantis’ expertise in innovation, global manufacturing, and distribution can significantly enhance the performance and cost profile of electric vehicles while improving supply chain resilience for batteries and EVs.”
Zeta Energy’s battery technology is designed for production using existing gigafactory infrastructure and will leverage a short, fully domestic supply chain in Europe or North America.
