Amprius’ latest proprietary silicon anode and cell design delivers a record-breaking 520 Wh/kg energy density, the highest known of any commercial battery today. Surpassing its 2024 breakthrough and offering nearly twice the energy of standard graphite cells (~260 Wh/kg), this design unlocks capabilities once impossible for electric flight. From next-generation drones to manned electric aircraft, it enables longer missions, greater range, and heavier payloads without added weight. This leap in performance is poised to transform aerospace, defense, and advanced mobility, redefining the future of battery-powered flight and accelerating cleaner, more sustainable forms of mobility.
