QuantumScape Expands Commercial Roadmap with Osprey, the Open All-Solid-State Platform for Battery Development

QuantumScape says Osprey opens new licensing and co-development options for existing customers and sulfide-based battery developers.

Rhea-AI Summary

QuantumScape (NASDAQ: QS) announced Osprey, an open platform for developing all-solid-state batteries that builds on its existing QSE platform.

Osprey combines the company’s ceramic separator and anode-free lithium-metal design with a solid cathode. In early testing, cells demonstrated 1,000 full charge cycles with approximately 80% capacity retention, charging from 10% to 80% in five minutes, and operation under one atmosphere of pressure. QuantumScape has tested cathodes developed internally and by automotive customers.

The company is already working with automotive partners on Osprey development and describes it as its long-term all-solid-state technology solution. Cells based on QSE are currently shipping to customers.

News Explained

Osprey’s 1,000-cycle result is specifically for a sulfide-based cathode tested at one atmosphere; the release says sulfide-based batteries have not yet produced commercially viable technology.

5 terms

all-solid-state technical

"its next-generation open platform for all-solid-state batteries"

Describes a device—most often a battery—whose electrolyte and separator are solid materials instead of a liquid or gel. In an all-solid-state battery ions move through a solid ionic conductor between the electrodes; that solid electrolyte replaces the flammable liquid found in conventional lithium-ion cells, changing how the cell is assembled, how electrodes contact each other, and how the device behaves under heat and mechanical stress.

lithium-metal technical

"QS proprietary ceramic separator and anode-free lithium-metal design"

Lithium-metal is the pure, metallic form of the element lithium used as an electrode material in batteries; compared with the more common graphite or lithium‑ion designs, it can store much more energy in the same space, like swapping a small suitcase for a larger one in the same overhead bin. For investors, lithium‑metal matters because it promises higher battery range and lighter weight for electric vehicles and portable electronics, but it also brings greater technical and safety challenges that affect development costs, production timelines and regulatory approval.

anode-free technical

"ceramic separator and anode-free lithium-metal design"

A battery cell design that has no preinstalled anode active material; instead the cell is assembled with a bare anode current collector (typically copper) and all the lithium is stored in the cathode at manufacture, so lithium metal plates onto and is stripped from the current collector during charge and discharge. This approach can raise theoretical energy density because it eliminates the conventional anode stack, but it also depends on precise control of lithium plating/stripping and electrolyte/formulation to avoid rapid loss of lithium inventory, dendrite formation, and short cycle life.

ceramic separator technical

"QS proprietary ceramic separator and anode-free lithium-metal design"

A ceramic separator is a thin, heat‑resistant layer placed between the positive and negative parts of a rechargeable battery to keep them apart while allowing ions to pass through. Think of it as a durable, porous firewall inside a battery that helps prevent short circuits and overheating, improving safety, lifespan and performance. Investors care because its use can affect a battery’s reliability, manufacturing cost and regulatory appeal, all of which influence product competitiveness and market adoption.

sulfide-based electrolytes technical

"Sulfides can react with lithium metal"

Solid electrolyte materials whose conducting ions move through a crystal or glass network that contains sulfur (sulfide) anions rather than oxygen or polymer backbones; they are used in solid-state batteries to carry lithium (or other alkali) ions between electrodes. Sulfide-based electrolytes typically offer high ionic conductivity and soft, deformable mechanical properties that aid contact with electrodes, but they are chemically sensitive to moisture (can release toxic hydrogen sulfide gas) and often require controlled handling and specific electrode interfaces during manufacturing.

SAN JOSE, Calif., Nov. 11, 2026 (GLOBE NEWSWIRE) -- QuantumScape Corporation (NASDAQ: QS), a global leader in solid-state lithium-metal battery technology, today announced Osprey: its next-generation open platform for all-solid-state batteries. Osprey cells have delivered the world’s first public data demonstrating a sulfide-based cathode cycling 1,000 times under just one atmosphere of pressure – an unmatched capability that is necessary for automotive solid-state batteries.

Osprey pairs the QS proprietary ceramic separator and anode-free lithium-metal design with a solid cathode, creating an all-solid-state cell. Osprey builds on the company’s QSE platform, and opens new licensing and co-development options for current QS customers and expanding its offering to developers of sulfide-based all-solid-state batteries.

QS technology has demonstrated an enhanced safety profile compared to conventional lithium-ion cells, along with low operating pressure and excellent energy retention. Osprey’s all-solid cathode, paired with the proprietary QS ceramic separator, enables additional performance benefits, including faster charging, operation across a wider range of temperatures, and projected energy densities up to ~1,100 Wh/L.

In early testing, Osprey cells have demonstrated:

• Cycle life: 1,000 full charge cycles with ~80% capacity retention under gold-standard testing conditions
• Fast charging: 10% to 80% in five-minutes
• Low pressure: Requires only one atmosphere of pressure
• Cold-weather performance: Operational to less than -20 °C (-4 °F)

More information, including test results and conditions, can be found in a new white paper.

The battery industry has long pursued all-solid-state batteries using sulfide-based electrolytes, but this has yet to result in a commercially viable technology. Sulfides can react with lithium metal, which shortens battery life, and they typically need to be held under high pressure to operate, which is impractical for vehicles and many other applications.

Osprey is conceived as an open platform capable of working with a range of cathode chemistries. QS has tested Osprey with all-solid cathodes developed both in-house and by its automotive customers, laying the groundwork for multiple technology pathways for solid-state battery development.

“Osprey is the result of years of frontier R&D efforts, and we’re excited to share it publicly for the first time,” said Dr. Siva Sivaram, president and CEO of QS. “The industry has invested heavily in sulfide-based batteries but keeps hitting the same fundamental limits. As the data shows, Osprey can address these limitations. We believe Osprey can unlock the full potential of all-solid-state batteries, and our goal is to make it the leading platform for solid-state battery development.”

QS is already working with partners across the automotive industry on development using the Osprey platform. Cells based on the company’s QSE platform are shipping to customers today, and Osprey represents its long-term technology solution for all-solid-state battery development.
