QuantumScape has announced Osprey, a platform for developing all-solid-state batteries. It combines the company’s proprietary anode-free technology and ceramic separator with a solid sulfide-based cathode. Unlike QuantumScape’s previous cells, which used a liquid component in the cathode, Osprey cells are fully solid-state.
Early lab tests showed Osprey cells endured 1,000 full-charge cycles. They retained about 80% of their capacity. The cells achieved this performance at one atmosphere of pressure, while other sulfide-based battery technologies typically require high pressure to operate.
Other demonstrated capabilities include charging from 10% to 80% in five minutes and operating in cold weather.
QuantumScape is positioning Osprey as an open platform for licensing and co-development with battery and automotive companies, including companies developing their own sulfide cathodes. The strategy aims to make QuantumScape’s separator technology a key component for the broader industry. The company has not announced a commercial timeline for Osprey.
