Recently, Stellantis announced a joint development agreement with Zeta Energy, a US-based lithium-sulfur battery technology company. The two companies will collaborate to develop lithium-sulfur batteries and accelerate their application in the EV sector.
According to the announcement, lithium-sulfur batteries are lighter than traditional batteries of the same volume, providing longer driving range, better handling, and higher performance. The technology also supports fast-charging, potentially increasing charging speed by 50%. In terms of cost, the price per kWh of lithium-sulfur batteries is expected to be less than half that of current lithium-ion batteries.
“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.”
Compared to traditional lithium-ion batteries, lithium-sulfur battery technology offers higher performance at a lower cost. Sulfur is abundant and inexpensive, which significantly reduces production costs and supply chain risks. Zeta Energy’s lithium-sulfur battery technology takes advantage of waste materials, methane, and unrefined sulfur (by-products from various industries) in its production process, eliminating the need for cobalt, graphite, manganese, or nickel, and significantly reducing CO2 emissions.
Zeta Energy’s lithium-sulfur batteries will be produced at existing super-factories, aimed at shortening supply chains in Europe or North America and fully localizing the power battery supply chain.
The partnership also includes pre-production development and future production planning, with the goal of having lithium-sulfur battery projects ready to power Stellantis’ EVs by 2030. Stellantis’ strategic plan, Dare Forward 2030, aims to introduce 75 battery-electric vehicles by 2030. Stellantis is employing a dual-chemistry approach to serve all customers and exploring innovative battery cell and pack technologies.
In addition to its partnership with Zeta Energy, Stellantis has also provided funding to support Lyten, another North American lithium-sulfur battery startup. Lyten announced in October that it would invest $1 billion (US) to build the world’s first lithium-sulfur battery gigafactory in Reno, Nevada and, with a planned capacity of 10 GWh. The first phase of the plant is expected to start production in 2027.
