Amprius partners with US Army to develop silicon anode batteries for unmanned aircraft


Amprius Technologies has been awarded a contract with the US Army’s Rapid Capabilities and Critical Technologies Office. The 18-month rapid prototyping contract includes the design, development, and validation of high-energy-density silicon anode lithium-ion batteries to be used in unmanned aircraft system applications.

Amprius offers a silicon anode battery with high energy density in commercially available cells. The company’s Si-Nanowire platform will be used in UAS, UAM and eVTOL applications. Based on an Armstrong & Associates market study, Amprius estimates the total battery market for UAS to be over $10 billion, increasing to over $30 billion by 2024.

“Amprius’s proven superiority in specific energy and energy density with Si-Nanowire allows us to enable unprecedented performance in drones, effectively doubling the operational endurance of UAS,” said Ionel Stefan, Amprius Chief Technology Officer.
