Amprius Technologies Inc. (NYSE: AMPX) announced a collaboration with Matternet to provide silicon anode lithium-ion batteries for drone delivery operations. Amprius cells are currently deployed in Matternet's M2 aircraft, with plans to extend the partnership to Matternet's next-generation platform.

The collaboration focuses on optimizing battery performance for commercial drone delivery operations. Amprius' silicon anode cells deliver up to twice the energy density of conventional graphite-based batteries, according to the company's press release statement.

"Amprius delivers best-in-class battery performance, and in drone delivery that translates directly into commercial advantage," said Andreas Raptopoulos, founder and CEO of Matternet.

The companies plan to work together on cell selection, form factor, thermal performance, charge rate, and cycle life optimization for Matternet's aircraft. The partnership aims to improve aircraft availability, expand service areas, and reduce cost per delivery as Matternet scales operations.

"By working closely with Matternet's engineering team, we can optimize our silicon anode technology for their aircraft, operating models, and cost-per-delivery objectives," said Tom Stepien, CEO of Amprius Technologies.

Matternet describes itself as the only FAA Type Certified drone delivery company and has conducted more than 60,000 commercial flights across urban and suburban environments in the U.S. and Europe. The company operates B2B healthcare delivery services and expanded into B2C drone delivery operations in Silicon Valley in 2024.

Amprius targets volume production readiness aligned with Matternet's fleet expansion plans beginning in early 2027. The Fremont, California-based company operates through a contract manufacturing strategy for scalable production.
