In a recent announcement on Dec. 5, Stellantis and Texas-based Zeta Energy have inked a deal to develop lithium-sulfur (Li-S) battery cells for Stellantis’ future electric vehicles (EVs). This collaboration targets the advanced technology of lithium-sulfur batteries, which boast roughly twice the energy density of current lithium-ion batteries and can enhance fast-charging speeds by up to 50%. The joint effort will include the pre-production phase, with Stellantis aiming to incorporate these batteries in its EVs by 2030.
In addition to faster charging times, lithium-sulfur batteries are expected to be significantly cheaper to produce per kilowatt-hour compared to lithium-ion batteries. Their increased energy density could allow the use of smaller, more affordable battery packs without compromising vehicle range, thereby improving the affordability of upcoming EV models. This collaboration aligns with Stellantis’ goal to achieve carbon neutrality by 2038 while maintaining high standards for range, performance, and vehicle cost.
Contrasting with lithium-ion batteries that rely on cobalt and nickel, lithium-sulfur batteries utilize plentiful waste materials such as unrefined sulfur and methane. This mitigates supply-chain risks by eliminating the need for cobalt, graphite, manganese, and nickel. Zeta Energy’s technology can also be manufactured on existing gigafactory lines, suggesting a streamlined supply chain in Europe or North America without dependency on critical raw materials.
The partnership leverages Stellantis’ robust expertise in innovation, manufacturing, and distribution, paired with Zeta Energy’s pioneering Li-S technology. This synergy aims to enhance the performance and cost-effectiveness of EVs while reinforcing supply chain resilience. Together, they seek to set a new benchmark in EV battery technology, contributing to a sustainable future in transportation.
