Houston-based Zeta Energy, a lithium-sulfur battery developer, has appointed Michael Everett as COO, the company said on May 2.

Everett has more than 20 years of experience in energy storage scaling and development. For more than 13 years, he served in various leadership positions, including CTO, at energy storage company Maxwell Technologies.

In his time at Maxwell, Everett coordinated multiple joint collaborations with third-party technology and product development companies. He also led the creation of customer-based commercialization programs.

Prior to Zeta, Everett also worked at Trojan Battery Co. as senior vice president of engineering and research, and he served as president and COO at Advanced Battery Concepts.

“Zeta is in the process of rapidly scaling up manufacturing for our game-changing lithium-sulfur battery technology, and Michael Everett is one of the few people in the world with experience in scaling both materials and battery manufacturing,” said Tom Pilette, CEO of Zeta Energy. “We think Michael will contribute enormously to Zeta's success."
