Stellantis Developing Lithium-Sulfur Electric Vehicle Batteries for Half the Cost

Stellantis has partnered with Zeta Energy to produce lithium-sulfur batteries for EVs that will be half the price of the lithium-ion batteries commonly seen in EVs today, according to Inside EVs.

Though lithium-sulfur batteries have been around for decades and are known to degrade quickly, the two companies are developing a new kind of lithium-sulfur battery that they claim will be able to offer the same energy as liquid-based lithium-ion batteries, as well as 50% more driving range and 50% faster charging sessions, but for half the price.

Additionally, the battery wouldn’t require cobalt, graphite, manganese, or nickel, but is instead made from waste materials, unrefined sulfur, and methane.

Development of the technology has already begun, with pre-production to follow before scaling production by 2030.

“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, chief engineering and technology officer at Stellantis. “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.”
