California-headquartered lithium-ion battery manufacturer Amprius has signed purchase orders for its SiMaxx cells from Airbus subsidiary AALTO, a Finland-headquartered producer of fixed-wing, high-altitude platform stations (HAPS).
Amprius says its 450 Wh/kg SiMaxx cells are designed to operate in extreme flight conditions while maximizing flight range and payload capacity. The batteries are capable of supplying enough endurance for persistent HAPS overnight stratospheric flight operations in all seasons or at higher latitudes.
“Zephyr relies on the most cutting-edge sustainable technology and design to push the boundaries of solar-powered, stratospheric flight,” said Pierre-Antoine Aubourg, AALTO’s Chief Technical Officer. “Amprius continues to produce ultra-high-energy-density batteries, enabling improvements in nighttime operations as well as the extent of coverage latitude.”
