Zeta Energy

Zeta Energy develops rechargeable batteries, using its advanced lithium-sulfur battery technology, for use in electric vehicles and grid energy storage. The company has developed both a proprietary cathode and anode for its battery system. Zeta’s carbon nanotube anode is integrated with its proprietary sulfurized carbon cathode to develop high-performance and low-cost battery cell technology. The company has also filed 30+ patents on its proprietary carbon nanotube anode and sulfur cathode technology. 

Zeta’s technology doesn’t comprise nickel, cobalt, manganese, or graphite. This reduces dependency and volatility in prices and the availability of materials. Moreover, all of Zeta’s materials are sourced closer to the company’s manufacturing locations, reducing supply chain constraints. The company aims to develop batteries that achieve over one thousand cycles with greater than 450 Wh/kg, at a cost of under USD 60/kWh, by 2025.

In May 2023, Zeta announced that it has developed a sulfurized carbon material compatible with dry-electrode processing. As such, the company is able to avoid the use of solvents entirely when producing electrodes and eliminated the need for drying. 

Key customers and partnerships

In November 2023, Zeta partnered with Huntsman Corporation to develop an advanced lithium-sulfur battery, which doesn't require copper or aluminum for current collection.

Funding and financials

In February 2024, Zeta secured a USD 4 million grant from the US Department of Energy's Vehicles Technology Office (VTO). The company intended to use the funding to advance and commercialize its high-capacity lithium-sulfur battery technology.

Prior to this, in January 2023, Zeta Energy received USD 4 million in federal funding to develop efficient EV batteries as part of the ARPA-E's EVs4ALL (Electric Vehicles for American Low-carbon Living) program. Prior to this in February 2022 the company raised USD 23 million in a Series A funding round led by Moore Strategic Ventures. The proceeds were used to expand the company’s laboratory facility in Houston and scale up the commercialization activities of its battery technology.
