Amprius Technologies announced it has delivered SiCore® battery cells to multiple advanced drone and unmanned aerial vehicle (UAV) customers from its Fremont, California pilot line on July 22, 2025. These shipments include 450 Wh/kg high-energy cells to Airbus subsidiary AALTO and balanced energy-and-power cells to other drone manufacturers supporting tactical and commercial missions. This marks another key milestone in the company's commercial scale-up.
Customer qualification often begins with prototype SiCore cells built at the Fremont facility, accelerating the transition from development to deployment for advanced applications. The newly shipped 450 Wh/kg SiCore cells are engineered to support even longer-duration flights, where energy density and weight are mission-critical. AALTO's Chief Technology Officer, Pierre-Antoine Aubourg, noted that Amprius's SiCore cells represent a major advancement in energy performance.
Amprius's Fremont headquarters serves as the company’s center for R&D, prototyping, and pilot-scale production, where the SiCore platform was developed and validated. While Fremont enables rapid development and early-stage production, Amprius is also scaling its global supply chain with over 1.8 GWh of manufacturing capacity through international contract partnerships, including a strategic agreement in South Korea.
