Company Overview

Zeta Energy Corp. is a United States–based developer and manufacturer of advanced lithium-sulfur batteries, established in 2014 in Houston, Texas. The company’s mission is to produce sustainable energy storage solutions for electric vehicle applications and renewable energy systems.

Battery Technology

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.

Products

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.

Recent Projects

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.

Investors

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.
