Amprius Technologies has launched a silicon-anode battery cell aimed at enhancing the endurance of uncrewed aircraft. The new SiCore cell boasts an energy density of 500 watt-hours per kilogram (Wh/kg) at a continuous discharge rate of 1C, with commercial availability anticipated in the fourth quarter of 2026. The company plans to provide both customer-specific and standard pouch formats for small uncrewed aircraft systems.
This development is significant as higher energy density in aviation can lead to longer flight times, increased range, or the ability to carry heavier payloads without adding battery weight. Amprius has previously achieved similar energy levels but faced challenges in scaling production. The SiCore platform aims to simplify the manufacturing process, allowing customers to transition from qualification to volume production without the need for specialized equipment.
Looking ahead, Amprius will initiate production at its Fremont, California facility and expand through global manufacturing partners. The company has a history of supplying battery cells to AALTO HAPS, which develops solar-electric aircraft. As energy density is crucial for long-duration flights, advancements in this area could significantly enhance operational capabilities for various applications, including fixed-wing drones and High-Altitude Platform Stations (HAPS).
