Zeta Energy’s lithium-sulfur batteries achieve 450 Wh/kg energy density (3× lithium-ion) at less than half the cost per kWh. They use 3D structured lithiated vertically-aligned carbon nanotube anodes to prevent dendrite formation and sulfurized carbon cathodes to avoid rare metals. Manufacturing incorporates waste materials and methane to significantly lower CO2 emissions.
Advanced lithium-sulfur battery cells featuring 450 Wh/kg energy density, up to 10C charge rate, 2000 full charge/discharge cycles, and <5% self-discharge per year.
In 2024, Zeta Energy partnered with Stellantis to integrate lithium-sulfur batteries into future electric vehicle models by 2030, targeting 50% faster fast-charging and scaling production via existing gigafactories in Europe and North America.
Zeta Energy Corp. has raised a total of $27M. In its 2022 Series A round, it secured $23M led by Moore Strategic Ventures. It also received grants from the U.S. Department of Energy in 2024 and investment from Footprint Coalition Ventures.
