Short answer: QuantumScape's new Osprey battery is a real lab result, not a product you can buy. On November 11, 2026, the company showed a small two-layer all-solid-state cell that lasted 1,000 full charge cycles and kept about 80% of its capacity while held at just 1 atmosphere of pressure. That is a first for this type of battery. But the headline 5-minute charge was done at 80°C (176°F), the cold-weather number came from a stamp-sized cell, the ~1,100 Wh/L energy figure is a projection, and there is no production date for Osprey. QuantumScape's first mass-production line, for its older QSE-5 cell, is targeted for 2028. If you need a car in the next two years, do not wait for solid-state. Investors got a strong science result and no new revenue timeline, which is why QS stock fell about 5% on the day.
What QuantumScape announced
Osprey is QuantumScape's (NASDAQ: QS) new "open platform" for all-solid-state batteries. It keeps the company's ceramic separator and "anode-free" lithium-metal design, and replaces the liquid inside the cathode with a solid sulfide material. That makes every layer of the cell solid. QuantumScape says it has tested Osprey with its own cathodes and with solid cathodes made by its automotive customers, and it wants to license the platform to other battery developers (press release).
One detail matters for anyone who has followed this company: its current product is not all-solid-state. In the white paper, QuantumScape describes its QSE-5 cell as a ceramic separator paired with "a relatively conventional high-nickel NMC cathode and a liquid catholyte." Osprey is the step that removes that liquid.
The headline numbers vs. how they were tested
QuantumScape published its test conditions, which is more than many battery startups do. Here is each claim from the press release next to what the white paper and Electrek's review of it show.
Press-release claim | How it was actually tested | How much it means for a car |
|---|---|---|
1,000 cycles, ~80% capacity kept | 2-layer cell, 50 x 65 mm cathode, full 0–100% cycles at 1C charge and discharge, 30°C, 1 atm | Strongest result. Real conditions, but a tiny cell (Electrek estimates ~0.3–0.4 Ah vs ~5 Ah for a QSE-5) |
10% to 80% in five minutes | 2-layer cell charged at 10C at 80°C (176°F) | Weak for now. EV packs are not preconditioned anywhere near that hot. No room-temperature result published |
Works below -20°C (-4°F) | Single-layer cell, 21 x 21 mm cathode, slow C/3 rate; kept 68% of room-temp capacity at -20°C, 85% at 0°C | Promising for a sulfide cell, but stamp-sized and gentle |
Up to ~1,100 Wh/L | Projection for large cells with high-loading cathodes; backing data from 11 mm coin cells at 3 atm, 100 cycles | Not demonstrated. QSE-5 today is rated 844 Wh/L |
Needs only 1 atm of pressure | Shown in the 1,000-cycle test | Important: rival sulfide cells often need roughly 20 to 100+ atm, which means heavy steel clamping in a pack |

Why the pressure number is the real story
Most big battery makers chasing solid-state, including Toyota, Samsung SDI and BYD, use sulfide electrolytes. Their problem has been that sulfide cells lose contact inside unless they are squeezed hard. QuantumScape's white paper illustrates that 20 atm on a single 10 x 24.2 cm cell works out to roughly 5,000 kg of force. Holding that across a whole pack takes thick end plates and tie rods, which adds weight, volume and cost, and eats into the range advantage solid-state is supposed to deliver.
Osprey's pitch is to keep the sulfide where it helps, inside the cathode, and let QuantumScape's ceramic separator handle the lithium metal. A 1,000-cycle run at 1 atm is the first public data of its kind for a sulfide cathode with a lithium-metal anode, according to QuantumScape, and Electrek said it could not find published data contradicting that.
When could this be in a car you can buy?
Not soon. Here is what the company itself has put on paper:
Osprey: no timeline. The white paper says the process works "at laboratory scale" and that "significant work remains in process engineering."
QSE-5 (the older, partly liquid design): samples are shipping from the Eagle Line pilot line in San Jose. A 100 MWh production line is targeted to start in 2028 (Q3 2026 shareholder letter).
Scale check: 100 MWh a year is roughly enough cells for about 1,000 to 1,500 EVs with typical 70–100 kWh packs, and QuantumScape says that line is aimed first at data-center and other non-auto customers. Car-scale volume depends on partners like VW's PowerCo and Honda licensing the tech and building gigawatt-hour factories.
Rivals: Samsung SDI targets sulfide solid-state mass production in the second half of 2027, BYD plans small batches in 2027, Toyota aims for 2027–2028, and CATL has said mass-market solid-state is still years away, around 2030 (as summarized by Electrek).
Even the most optimistic of those plans means low-volume, expensive cars first. Mainstream, affordable solid-state EVs are a late-2020s to 2030s story.
Should you wait for solid-state before buying an EV?
No, for almost everyone. Today's lithium-ion EVs already do much of what solid-state promises. Real-world data shows modern packs holding up well past 100,000 miles (see our guide to how long EV batteries really last and Ford's Mustang Mach-E battery-health data). Many 800-volt EVs already charge 10–80% in roughly 18–20 minutes, and current models already go 300+ miles on the EPA cycle. Waiting four or more years for a first-generation, premium-priced battery means four years of paying for gas.

Worried about battery wear? Most EV batteries carry an 8-year/100,000-mile warranty (check the exact terms). For used EVs, ask for a battery-health report.
Hot climate (like Arizona): a liquid-cooled pack matters more than chemistry hype. Price home charging on our EV cost calculator and plan road trips with the Arizona EV charging map.
Leasing is a hedge: if you truly believe battery tech will jump in 3 years, a lease lets you drive electric now and switch later without resale risk.
What it means for QS investors
The market's reaction tells you how it read the news. QS shares closed at $4.21 on November 11, down about 5.4% on heavy volume of roughly 26 million shares (Yahoo Finance), after briefly trading higher in the morning (Benzinga). The stock hit a 52-week low of $3.80 on October 15.
Numbers from QuantumScape's own Q3 2026 shareholder letter worth keeping next to the headlines:
Metric (Q3 2026) | Figure |
|---|---|
Customer billings | $9.8 million (not GAAP revenue) |
Adjusted EBITDA loss | $60.7 million |
GAAP net loss | $84.5 million |
Liquidity at quarter end | $819.8 million |
2026 Adjusted EBITDA loss guidance | $250–275 million |
First mass-production line | 100 MWh, targeted for 2028 |
The bull case: Osprey turns QuantumScape from a sulfide skeptic into a supplier to the sulfide camp. If Samsung SDI-, Toyota- or BYD-style programs license the ceramic separator, QS could earn royalties without building giant factories itself.
The bear case: there is no Osprey revenue, customer or date yet. The Q3 letter says QS is still aligning its statement of work with VW PowerCo, and its risk factors flag that the two may not agree on updated milestones. Spending of roughly $60 million a quarter means more fundraising, and dilution, is possible before any royalties arrive.
What to watch: a named Osprey licensing deal, independent test data on larger multi-layer cells, a room-temperature fast-charge result, and any update to PowerCo milestones.
This is not investment advice. Read the company's SEC filings before buying or selling any stock.
FAQ
Is the QuantumScape Osprey battery in any car today?
No. Osprey is a lab-scale platform with no production date. QuantumScape's older QSE-5 cells are shipping only as samples to partners.
Is QSE-5 a solid-state battery?
Partly. It uses a solid ceramic separator and a lithium-metal anode, but its cathode still contains a liquid catholyte, according to QuantumScape's own white paper. Osprey is the all-solid version.
Can Osprey really charge in five minutes?
QuantumScape showed a 10–80% charge in about five minutes, but at 80°C (176°F) in a small two-layer cell. It has not published a room-temperature five-minute result.
When will solid-state EVs be affordable?
Most battery makers point to 2027–2028 for small, premium first runs and around 2030 for mass-market volume. Expect the first cars to be expensive.
Will today's EVs become obsolete when solid-state arrives?
Unlikely in practice. Gas cars did not become worthless when better engines arrived, and current EV batteries are lasting well beyond their warranties. Resale values depend far more on price cuts and incentives than on next-generation chemistry.
