Stellantis and Houston-based battery manufacturer Zeta Energy have announced a joint development agreement aimed at advancing battery cell technology for EV applications. The partnership aims to develop lithium-sulfur EV batteries with game-changing gravimetric energy density while achieving a volumetric energy density comparable to today’s lithium-ion technology.
For customers, this means potentially a significantly lighter battery pack with the same usable energy as contemporary lithium-ion batteries, enabling greater range, improved handling and enhanced performance. Additionally, the technology has the potential to improve fast-charging speed by up to 50 %, making EV ownership even more convenient. Lithium-sulfur batteries are expected to cost less than half the price per kWh of current lithium-ion batteries.
The batteries will be produced using waste materials and methane, with significantly lower CO2 emissions than any existing battery technology. Zeta Energy battery technology is intended to be manufacturable within existing gigafactory technology and would leverage a short, entirely domestic supply chain in Europe or North America.
The collaboration includes both pre-production development and planning for future production. Upon completion of the project, the batteries are targeted to power Stellantis EVs by 2030.
“We are very excited to be working with Stellantis on this project. 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.”
