QuantumScape unveils Osprey all-solid-state cell: 1,000 cycles at 1 atm

QuantumScape (QS) is finally going all-solid-state. Its new Osprey platform swaps the liquid in its cathode for a sulfide solid electrolyte, and the company says the cells have hit 1,000 full cycles to 80% capacity at just one atmosphere of pressure.

That’s a big deal for the sulfide camp, which includes Toyota, Samsung SDI, BYD, and Factorial. Their cells typically need heavy clamping to work. But the white paper behind the announcement shows these are small, early lab cells, and some headline numbers come with important conditions.
