Zeta Energy Corp. is a U.S.-based developer and manufacturer of advanced lithium-sulfur batteries, established in 2014 in Houston, Texas. The company has created an innovative battery technology that surpasses traditional lithium-ion batteries in both performance and cost-effectiveness. By eliminating the need for critical materials such as cobalt, nickel, manganese, and graphite, Zeta Energy’s solutions offer significant advantages in terms of energy density and environmental impact. The company focuses on producing sustainable energy storage solutions that support the growing demand for electric vehicle applications and renewable energy systems.
Battery Technology
Zeta Energy’s lithium-sulfur batteries represent a significant advancement in energy storage technology. These batteries achieve an impressive energy density of 450 Wh/kg, which is three times higher than conventional lithium-ion batteries, while costing less than half per kilowatt-hour. The technology utilizes 3D structured metallic anodes made from lithiated vertically-aligned carbon nanotubes, which prevent dendrite formation and enhance performance.
The cathodes employ sulfurized carbon material, providing exceptional stability and high sulfur content without relying on rare metals. This design reduces cost volatility and minimizes geopolitical dependencies associated with raw material sourcing. The batteries maintain a charge rate of up to 10C and demonstrate 2000 full charge/discharge cycles, with a self-discharge rate below 5% after one year.
The manufacturing process incorporates waste materials and methane, resulting in significantly lower CO2 emissions compared to traditional battery production methods. This approach aligns with environmental sustainability goals while maintaining high performance standards.
Recent Projects
In February 2024, Zeta Energy formed a strategic partnership with Stellantis to integrate their lithium-sulfur batteries into future electric vehicle models. This collaboration aims to implement the technology in Stellantis vehicles by 2030, with potential improvements in fast-charging speeds by up to 50%. The partnership focuses on scaling production using existing gigafactory infrastructure while maintaining the benefits of a domestic supply chain in Europe and North America.
Investors
Zeta Energy has secured substantial financial backing through multiple funding rounds, totaling $27 million. Moore Strategic Ventures led a significant Series A funding round of $23 million in February 2022. The company has also received support from the U.S. Department of Energy through various grants, including a Grant – II funding round in February 2024. Footprint Coalition Ventures has also invested in the company, supporting its technological development and commercialization efforts.
