Netherlands car manufacturer, Stellantis, and US battery technology company, Zeta Energy, have signed a joint development agreement to develop lithium-sulphur EV batteries with higher capacity compared to lithium-ion technology.
Collaboration includes pre-production development and future production planning. Stellantis aims to use batteries in its cars by 2030.
Lithium-sulphur battery technology has the potential to create a lightweight battery pack with the same usable capacity as lithium-ion batteries, allowing greater driving range, improved handling and improved performance. The technology may improve the fast charging speed by up to 50%. Sulphur, being widely available and inexpensive, reduces production costs and procurement risks. Lithium-sulphur batteries are expected to cost less than half the price per kWh of current lithium-ion batteries.
Zeta's lithium-sulphur battery design uses waste materials, methane and unrefined sulfur, a byproduct from various industries, and requires no cobalt, graphite, manganese or nickel. The technology is intended to be able to be produced within existing gigafactories and will use a short, complete domestic chain in Europe or North America.
“The combination of Zeta Energy's lithium-sulfur battery technology with Stellantis' innovative technology, global manufacturing and distribution can improve the performance and cost profile of electric vehicles while increasing the resilience of the supply chain for batteries and EVs,” said Tom Pilette, CEO of Zeta .
