SES AI signs staged H1-X battery-development framework with Doroni Aerospace
SES AI entered a framework agreement worth up to $1.09 million to design and develop battery packs for Doroni Aerospace's H1-X personal eVTOL, with work released in stages through purchase orders.
Evidence notes
- The framework runs through staged purchase orders during 2026 and 2027; only an initial $65,000 tranche is committed, so the $1.09 million figure is a maximum rather than a firm order.
- SES AI will provide battery systems for Doroni's ground- and flight-test campaign, with a path to testing as early as 2027 and options for additional test systems and serial production.
- The development work combines high-energy cells approaching 400 Wh/kg with battery-health monitoring and abuse testing for the H1-X programme.
Company context
SES AI develops Li-metal and lithium-ion battery cells, materials and battery-management software for drones, urban air mobility, robotics and energy storage.
