High-energy cells support long-endurance UAV missions for Airbus subsidiary AALTO and others<\/h3>\n

Amprius Expands Drone Battery Shipments from Fremont Pilot Line<\/h4>\n

Amprius Technologies, Inc. has delivered its high-energy\u00a0silicon anode battery cells to several advanced drone and UAV manufacturers, including Airbus subsidiary AALTO. The shipments mark a major milestone in the company\u2019s scale-up efforts to meet growing industry demand for lightweight, high-endurance power solutions.<\/p>\n

\"Amprius<\/p>\n

The\u00a0SiCore\u00ae batteries were produced at Amprius\u2019 Fremont, California pilot facility, which serves as the company\u2019s center for research, development, and early-stage production. The new deliveries include 450 Wh\/kg energy-dense cells for high-altitude platforms, as well as balanced energy-and-power cells for commercial and tactical UAV applications.<\/p>\n

Supporting Long-Endurance Missions<\/h4>\n

Pierre-Antoine Aubourg, chief technology officer at AALTO, emphasized the importance of Amprius\u2019 technology for stratospheric operations. \u201cAmprius\u2019 SiCore cells represent a major advancement in energy performance, supporting the ultra-lightweight, long-endurance requirements of our high-altitude operations,\u201d said Aubourg. \u201cTheir silicon anode technology has already enabled Zephyr to operate in the stratosphere overnight for months at a time, an unprecedented milestone in persistent flight. We look forward to working with Amprius as we qualify their next-generation cells to power the future of Stratospace innovation.\u201d<\/p>\n

AALTO\u2019s Zephyr platform is one of several high-altitude, long-endurance (HALE) systems benefiting from the performance gains of Amprius\u2019 silicon anode batteries. The cells allow for greater energy storage without added weight\u2014a key requirement for extended UAV missions in defense, communications, and environmental monitoring.<\/p>\n

Meeting Industry Demand and Scaling Production<\/h4>\n

Dr. Kang Sun, CEO of Amprius Technologies, stated that demand from drone manufacturers continues to grow. \u201cWe are expanding our pilot production in Fremont to meet a strong increase from leading drone manufacturers,\u201d he said. \u201cShipping our industry-leading SiCore cells to AALTO and other leading drone OEMs marks another key milestone in our commercial scale-up. From high-energy HAPS cells to balanced-performance drone batteries, we\u2019re now delivering solutions that meet a wide range of advanced mission needs.\u201d<\/p>\n

The Fremont site developed the SiCore platform, including a high-power 370 Wh\/kg cell designed for compact, mission-ready applications. Amprius\u2019 pilot facility enables fast customer qualification and accelerates the path from prototype to deployment.<\/p>\n

Building Global Capacity for Broader Adoption<\/h4>\n

While Fremont supports innovation and prototyping, Amprius is also building out its global supply chain to support higher-volume production. The company has secured over 1.8 GWh of manufacturing capacity through international partnerships, including a strategic contract in South Korea. This capacity expansion aims to meet rising demand from aerospace, defense, and electric mobility customers.<\/p>\n

Amprius produces some of the industry\u2019s highest energy-density lithium-ion batteries, with third-party-verified performance reaching 500 Wh\/kg and 1,300 Wh\/L. These advancements position the company to supply next-generation battery solutions across multiple sectors where power-to-weight ratio is critical.<\/p>\n
