QuantumScape unveils Osprey, an all-solid-state battery platform it says cycled 1,000 times at 1 atmosphere ↗
All-solid-state batteries have long been stuck on two problems: promising sulfide materials can react with lithium metal, and they often need high pressure to work, which is hard to do in a car. On November 11, QuantumScape announced Osprey, an open all-solid-state platform, saying its cells have produced the first public data of a sulfide-based cathode cycling 1,000 times under just one atmosphere of pressure. It also cites a projected energy density of up to about 1,100 Wh/L. These are the company's laboratory results. Osprey is a long-term technology platform, not a mass-produced car battery.
