QuantumScape has introduced Osprey, an open platform designed for the development of sulfide-based solid-state batteries. The platform integrates the company’s ceramic separator and anode-free lithium-metal design, allowing partners to utilize proprietary or third-party cathode technologies.
During initial testing, Osprey cells demonstrated 1,000 full charge cycles with approximately 80% capacity retention. The cells achieved a 10% to 80% charge in five minutes under standard conditions, with an energy density of up to approximately 1,100 Wh/L.
The company is currently collaborating with automotive partners on development projects using the new platform. While the results were achieved with two-layer test cells, mass production will require scaling to larger prismatic designs with more layers and increased surface area.
QuantumScape’s business model focuses on licensing its technology rather than large-scale manufacturing. The company previously launched the QSE-5 cell, which features a 5 Ah capacity and an energy density exceeding 844 Wh/L, with pilot production currently underway in San Jose.
