Amprius Technologies, Inc. is preparing to supply commercial level shipments of high energy density lithium-ion battery cells to AeroVironment for versions of the newly released Switchblade 300 Block 20 system.

The battery cells will deliver a longer run time for the advanced aviation application. 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.

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.

“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’ 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.”
