NEW YORK--( BUSINESS WIRE )--Archer Aviation Inc. (NYSE: ACHR), a leader in electric vertical takeoff and landing (eVTOL) aircraft, today announced it has signed a Space Act Agreement with the National Aeronautics and Space Administration (NASA). The collaboration will kick off with an initial project focused on studying high-performance battery cells and safety testing targeted for Advanced Air Mobility (AAM) and space applications. Archer believes that while the supply chain for electric vehicles in the U.S. is maturing, the supply chain for electric aircraft remains nascent not just here in the U.S., but globally, so this testing will help push progress forward. NASA's goal is to test Archer's battery cell and system design and share the results to push the entire AAM industry forward. Maturing battery technology is anticipated to be a key enabling factor for the mass production and adoption of electric aviation.
