Amprius to Supply Key Power Element for AeroVironment’s Switchblade 300 Block 20 Loitering Missile

April 12, 2023

Next-Generation Battery Cells Expected to Significantly Increase Run Time
for Tactical Missile System

FREMONT, Calif.– April 12, 2023Amprius Technologies, Inc. (“Amprius” or the “Company”) (NYSE: AMPX), a leader in next-generation lithium-ion batteries with its Silicon Anode Platform, is preparing to supply commercial level shipments to AeroVironment (NASDAQ: AVAV) in support of the company’s Switchblade 300 Block 20 loitering missile system.

Amprius is providing high energy density lithium-ion battery cells to power versions of AeroVironment’s newly released Switchblade 300 Block 20 system, delivering unparalleled run time for the advanced aviation application. The integration of these lightweight battery cells into the Block 20 system is expected to increase the flight time by at least 50% – allowing for longer endurance and extended loitering capability.

“This partnership with AeroVironment further validates the potential of our silicon anode technology for advanced aviation and defense applications,” said Dr. Kang Sun, Chief Executive Officer of Amprius. “We look forward to continuing to work with the AeroVironment team to greatly improve flight time of their tactical missile systems.”

Amprius began delivering cell shipments as a supplier to AeroVironment in 2022 and is fulfilling additional commitments for the future. AeroVironment is currently integrating Amprius cells into some defense products and is a strategic investor in the Company.

“Amprius’ battery cells have the power capabilities to transform the range and mission time for our applications,” said Brett Hush, AeroVironment’s vice president and product line general manager of tactical missile systems. “This capability could allow operators to deploy loitering missile systems from a greater range to identify threats and deliver a precision lethal payload with minimal collateral effects.”
