- Strategic Collaboration: Amprius and Matternet have formed a strategic partnership to enhance drone delivery performance using high-energy density silicon anode batteries, aiming for improved economic efficiency and operational effectiveness in Matternet's future drone platforms.
- Battery Performance Advantage: Amprius' silicon anode cells deliver up to twice the energy density of conventional graphite batteries, a critical advantage in aviation that directly impacts drone range, payload capacity, and overall economics.
- Commercial Operations Expansion: By optimizing the battery system to fit Matternet's aircraft architecture and delivery network, the partnership is expected to improve aircraft availability, expand service areas, and reduce cost per delivery, supporting Matternet's growth plans.
- Future Production Readiness: With Amprius cells already integrated into Matternet's M2 fleet, both companies are focused on deeper integration for the next-generation platform, targeting volume production readiness by early 2027 to support fleet expansion.
