Amprius’ High-Power Silicon Batteries Selected by ESAero to Power Next-Generation UAVs

Amprius Technologies, Inc. (“Amprius” or the “Company”) (NYSE: AMPX), a leader in next-generation lithium-ion batteries with its Silicon Anode Platform, announced Empirical Systems Aerospace, Inc. (ESAero), a leading producer of Unmanned Aerial Systems (UAS) and Advanced Air Mobility (AAM) platforms, chose the Amprius SiCore SA08 cell for integration into battery packs powering unmanned aerial vehicles (UAV) supporting defense, security, logistics, and public safety applications.

Amprius’ high-power cell was selected by ESAero for its ability to significantly increase flight times and payload capacity, which are essential for UAV platforms operating in demanding environments. The SA08 cell is available in volume today, allowing ESAero to accelerate the development and integration of Amprius’ cells into its UAVs.

“Amprius offered the best combination of advanced battery technology, production readiness, and cost competitiveness to meet the demands of this program,” said Andrew Gibson, CEO and President of ESAero. “Their silicon anode cells deliver the performance and reliability needed to accelerate our path from development to production while setting a new benchmark for what our battery packs can achieve for both our in-house and customer platforms. Amprius’ cells have enabled ESAero to create and maintain industry leading Group I and Group II UAV endurance.”

“This collaboration highlights the momentum Amprius is building across the UAV space,” said Dr. Kang Sun, CEO of Amprius Technologies. “By growing our production capacity through strategic partnerships, we’re delivering customers high-performance silicon anode cells at scale and at a competitive price. This allows companies like ESAero to develop more capable battery packs for aircraft, flying farther, carrying more, and operating more efficiently in the field.”

Amprius’ SiCore SA08 battery cells have successfully completed formal qualification and are now integrated into ESAero’s products. Building on this success, Amprius is gaining additional traction with other UAV partners, further solidifying its position as a leading solution for next-generation electric aviation platforms.
