Amprius gets $1.9M contract from U.S. Army to develop high-energy batteries

Amprius Technologies announced that it was selected by the U.S. Army to develop a large form factor 500 Wh/kg SiMaxx high-energy cell for electric mobility applications in the defense sector. The $1.9M contract that comes with the award will be used over the next 18 months to create the large form factor prototype 500 Wh/kg SiMaxx cell…”Amprius’ 500 Wh/kg SiMaxx cell provides the energy density required to enable broad application objectives on our solar HAPS performance roadmap,” said Dex Halpin, Vice President and General Manager of AV’s HAPS division. “Our partnership with Amprius allows AV to field our solar stratospheric platforms with the highest payload capability in its class: 150 lb mass and 1500W continuous power. The SiMaxx cell’s proven performance gives us confidence that our partnership with Amprius will help expand our solar platforms’ performance and payload capabilities for government and commercial customers.” Amprius’ industry-leading 500 Wh/kg, 1300 Wh/L SiMaxx cell has been verified by Mobile Power Solutions and provides approximately double the energy compared to conventional cells. The continued partnership with the Department of Defense accelerates the development of critical capabilities and strengthens the U.S. supply chain.
