Signal brief

QuantumScape unveiled Osprey, an open all-solid-state battery platform that the company says achieved 1,000-cycle sulfide-cathode cycling at one atmosphere and early metrics including ~80% retention, five-minute 10→80% charging, and projected ~1,100 Wh/L energy density.

• QuantumScape announced Osprey, its next-generation open platform for all-solid-state batteries.
• Osprey cells have demonstrated a sulfide-based cathode cycling 1,000 times under one atmosphere of pressure.
• In early testing Osprey cells showed ~80% capacity retention after 1,000 full charge cycles, 10% to 80% charging in five minutes, operation below -20 °C, and projected energy densities up to ~1,100 Wh/L.
• Osprey pairs QS’s proprietary ceramic separator and anode-free lithium-metal design with a solid cathode and is presented as an open platform for licensing and co-development.
