Amprius Technologies announced that Nordic Wing, a leading European drone manufacturer, has selected its high-energy-density SiCore® cells to power the ASTERO ISR fixed-wing unmanned aerial vehicle. Following a successful evaluation and qualification process, the SiCore cells delivered a 90% increase in flight endurance compared to conventional graphite cells, extending mission time up to four hours without adding weight and improving surveillance and mapping capabilities.
“Amprius’ batteries have fundamentally changed how our drones operate in the field,” said Jonas Dyhr, founder of Nordic Wing. “With a significant increase in flight time, our drones can stay airborne longer, cover more ground, and deliver real-time intelligence without interruptions. This enhanced endurance doesn’t just improve performance; it redefines what’s possible in every mission and can mean the difference between success and failure.”
“Energy is rapidly becoming a critical factor in drone operations,” said Tom Stepien, president of Amprius Technologies. “As mission requirements grow more complex, the need for lightweight, long-lasting, and dependable battery solutions continues to rise. Amprius is proud to be at the forefront of this evolution, delivering next-generation batteries that meet the dynamic needs of our defense partners like Nordic Wing.”
This partnership demonstrates a growing demand for advanced battery technologies in the UAV market, where energy density and weight are critical factors. As defense and commercial entities expand the use of unmanned systems for surveillance, mapping, and other operations, battery innovation will play a pivotal role in extending mission capabilities and reducing operational constraints. Both companies plan to continue collaboration to integrate next-generation energy storage solutions into future UAV platforms.
Amprius Technologies, headquartered in Fremont, California, manufactures high-energy and high-power lithium-ion batteries featuring silicon anodes. Its commercially available SiCore® and SiMaxx™ cells deliver up to 450 Wh/kg and 1,150 Wh/L, with third-party validation at 500 Wh/kg and 1,300 Wh/L. To meet growing demand, the company has secured over 1.8 GWh of contract manufacturing capacity and operates both an R&D laboratory and an MWh-scale manufacturing facility for silicon anode and cell production.
Nordic Wing specializes in advanced intelligence, surveillance, and reconnaissance systems, focusing on innovation and reliability in defense applications.
