SES AI Enters into Framework Agreement with Doroni Aerospace to Design and Develop a Battery Pack for Doroni Aerospace's H1-X Personal eVTOL

Framework agreement targets up to $1,090,000 in several stages for designing battery systems, with options for expanded testing and serial production

WOBURN, Mass.--(BUSINESS WIRE)--$SES #AI--SES AI Corp. (NYSE: SES) (“SES AI” or the “Company”), a leader in AI-enhanced Li-Metal and Li-ion batteries, today announced that it has entered into a framework agreement with Doroni Aerospace, developer of the H1-X two-seat personal electric vertical takeoff and landing (eVTOL) aircraft, to design, develop, test and deliver a battery pack for Doroni Aerospace’s H1-X. The framework agreement establishes an aggregate price of up to $1,090,000, of which the initial tranche of $65,000 is committed, for work planned over multiple stages in 2026 and 2027, with each stage to be triggered by the issuance of a purchase order from Doroni to SES AI.

Under the framework agreement, upon issuance of purchase orders from Doroni, SES AI will design and develop H1-X battery systems to power the aircraft’s ground and flight-test campaign — building a path to H1-X testing as early as 2027. The agreement includes options to expand into additional test systems and serial production.

Under the program, SES AI will design and develop battery packs built on high energy density cells developed through its Molecular Universe AI platform — with cell energy densities approaching 400 Wh/kg and safety validated through abuse testing including nail penetration, overcharge and external short circuit, and paired with SES AI’s enabled battery health monitoring.

“Doroni is a remarkable eVTOL developer, leading the charge on American-made personal electric aviation,” said Qichao Hu, Founder and CEO of SES AI. “The H1-X is exactly the kind of aircraft our aviation battery platform was built to power. We are proud to collaborate with Doroni Aerospace as its battery designer and developer, and we look forward to supporting Doroni from flight test through serial production.”

“We have reviewed various candidates for designing and developing our battery pack, and SES AI came out ahead where it matters most for the H1-X: performance, safety, and compliance,” said Doron Merdinger, Founder and CEO of Doroni Aerospace. “We are excited to initiate this collaboration with SES AI, who we believe can support Doroni Aerospace in the course of developing the battery pack for the H1-X with the ability to scale such design and development towards testing and serial production.”
