Amprius and Matternet expand partnership to integrate silicon anode batteries into drone delivery aircraft

Amprius Technologies silicon anode lithium-ion cells now power Matternet's M2 drone, with the companies planning deeper integration into Matternet's next-generation platform, targeting production readiness aligned with Matternet's planned fleet expansion beginning in early 2027.

Amprius silicon anode cells can deliver up to twice the energy density of traditional graphite-based lithium-ion batteries, which in aviation applications can reduce battery weight while increasing aircraft endurance and payload capability.

Matternet has conducted more than 60,000 commercial flights across the U.S. and Europe and was the first drone delivery operator to receive FAA Type Certification for a delivery drone platform in the United States.
