New EV Battery Pairs Five-Minute Charging with Operation Below −4°F
The company says the open platform keeps its anode-free design and showed a 2-layer cell reaching 80% capacity after 1,000 cycles.
- On Wednesday, Nov. 11, 2026, QuantumScape Corporation announced Osprey, its next-generation open platform for all-solid-state batteries combining a ceramic separator, anode-free lithium-metal design, and solid cathode.
- Sulfide-Based batteries typically require high pressure to operate, which is impractical for vehicles, while sulfides also react with lithium metal and shorten battery life. Osprey addresses these fundamental limitations.
- Osprey cells completed 1,000 full charge cycles at one atmosphere of pressure with about 80% capacity retention. "Osprey is the result of years of frontier R&D efforts," said Dr. Siva Sivaram, president and CEO of QuantumScape.
- QuantumScape is pitching Osprey as an open platform, creating licensing and joint development opportunities for existing customers and developers of sulfide-based batteries. The company has tested Osprey with solid cathodes from automotive partners.
- CATL, the world's largest battery maker, stated in June that true mass-market solid-state batteries are still "years away," around 2030. Significant work remains in process engineering before Osprey reaches commercial viability.

Solid State EV Batteries Have A Sulfide Problem...Or Not
Federal policy makers orchestrated an EV sales crash in the US last year, only to see electrification stakeholders gradually piece together a comeback focusing on cars that hit the affordability MSRP of $30,000 or less. New, higher-performing solid-state EV batteries are also inching their way into the market, the US startup Quantumscape contributing some fresh news. To Be Or Not To Be A Solid-State Battery As commonly understood, a solid-state …
QuantumScape (NASDAQ: QS) Breaks Sulfide Battery Barrier With Osprey Platform Capable Of 1,000 Cycles At One Atmosphere
A persistent technical wall has blocked sulfide-based solid-state batteries from reaching commercial viability for years, and QuantumScape Corporation (NASDAQ: QS) says its newly unveiled Osprey platform is designed to knock it down. The San Jose-based battery developer announced Osprey on November 11, 2026, describing it as an open, next-generation platform built around all-solid-state cell architecture […]
QuantumScape has found a way to curb the main problem of solid-state batteries and is ready to share the technology
The American company QuantumScape, backed since its inception by one of Bill Gates’ foundations and Volkswagen, has introduced a new Osprey platform for the development of all-solid-state batteries (ASSB). QuantumScape already produces promising wet batteries and is ready to move […]Read more at Aroged
