Stellantis signs Zeta Energy for lithium sulfur EV batteries
Cette publication existe aussi en Français
European car maker Stellantis has signed a deal to develop fast charging lithium sulfur batteries that could be lighter and cost less than half the price per kWh of current lithium-ion batteries.
The deal with Zeta Energy in the US includes both pre-production development and planning for future production by 2030 and would use waste materials and methane to reduce the carbon footprint. The process is intended to be manufacturable within existing gigafactory technology to create a short, entirely domestic supply chain in Europe or North America.
The cells use carbon nanotubes on the anode and a sulfurized carbon cathode to achieve an energy density of 450Wh/kg and show a lifetime of 200 charging cycles with a fast charging rate of 10C to charge in 6 minutes.
Stellantis is employing a dual-chemistry approach to serve all customers and exploring innovative battery cell and pack technologies. It already has deals for sulfur batteries with Lyten which is building a gigafactory in the US and with Factorial for solid state sulfide batteries, and is backing UK startup Tiamat for sodium cells.
“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.”
“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’ unrivaled expertise in innovation, global manufacturing and distribution can dramatically improve the performance and cost profile of electric vehicles while increasing the supply chain resiliency for batteries and EVs.”
