Zeta Energy has appointed Dr Boris Maslov as chief executive officer, as the US-based developer of lithium-sulfur batteries looks to accelerate commercialisation and scale-up of its technology.
The Houston-headquartered company said Maslov will lead the next phase of growth, including expanding partnerships and advancing its battery platform towards broader deployment.
Maslov brings experience from leadership roles
Maslov brings more than 30 years’ experience across the energy, semiconductor and artificial intelligence sectors. His career has included leadership roles at companies such as Ecron, EnergyOne Management, Flex Power Generation and Ener-Core, before moving into AI-focused firms including iGlass Technology and POLYN Technology.
“We are thrilled to welcome Dr. Boris Maslov to Zeta Energy as Chief Executive Officer,” said Charles Maslin, founder and chairman of the board. “His extensive experience building and scaling technology companies is a perfect fit for this growth period at Zeta, and we are excited that he will lead the next chapter of Zeta’s development.”
Maslov succeeds Tom Pilette, who has stepped down from the role. Maslin added: “Former CEO Tom Pilette has stepped down to take on new challenges, and we are grateful for his many contributions at Zeta and wish him the best.”
Zeta Energy is developing lithium–sulfur batteries designed to offer higher energy density while reducing reliance on critical materials. According to the company, its technology eliminates the need for graphite, cobalt, manganese and nickel, positioning it as a potential alternative for applications where supply chain constraints and cost are key considerations.
The company’s approach is based on a carbon nanotube anode combined with a sulfur cathode, supported by a patent portfolio of more than 60 patents and applications. It has previously received funding and recognition from organisations including ARPA-E and the US National Energy Technology Laboratory.
Zeta said its batteries have attracted interest particularly in aerial and defence applications, where energy density and weight are critical performance factors.
