Zeta Energy Demonstrates Industry-Leading Progress in Lithium-Sulfur Batteries

HOUSTON, Oct. 23, 2023 /PRNewswire/ -- Zeta Energy announced today that it has demonstrated a multilayer 300 Wh/kg pouch cell with up to 20 Ah. Zeta Energy's cells use an innovative lithiated vertically-aligned carbon nanotube anode and a Zeta's patented sulfurized carbon cathode. Zeta Energy is the only lithium-sulfur battery company to have received third-party verification that its technology avoids the polysulfide-shuttle effect.

The company also has clear line of sight to batteries that exceed 450 Wh/kg and 800 Wh/L, which it will produce in its pilot plant that is scheduled to be operational in 2024. These metrics make Zeta Energy the front runner in the race to achieve a lower-cost, high cycle-life lithium-sulfur battery. It also is the only company to have a complete battery system (anode and cathode) with a wholly domestic supply chain.

As noted by CEO Tom Pilette, "We demonstrated more than three years ago that our technology stops the polysulfide-shuttle effect in lithium-sulfur batteries, opening up the opportunity for batteries that both have extremely high density and are long lasting. We are seeing incredible progress with our battery development and expect to have batteries that achieve over one thousand cycles with greater than 450 Wh/kg, at a cost of under $60/kWh, commercially available in 2025."

In the last year Zeta Energy's efforts have been focused on scaling up materials manufacturing and refining their production processes. The company introduced a dry process for electrode coating, and the ability to grow vertically aligned carbon nanotubes on both sides of a current collector simultaneously.
