US EditionThis New EV Battery Can Charge to 80 Percent In Just 5 Minutes
Independent tests by VTT show Donut Lab's solid-state battery charges from 0 to 80% in 4.5 to 9.5 minutes while retaining nearly full capacity without active cooling.
- Donut Lab released VTT's first independent test showing the cell charged 0–80% in 4.5 minutes at 11C.
- Donut Lab, a Finnish startup, announced earlier this year it was on the cusp of a major breakthrough, prompting skepticism, so it commissioned VTT to independently verify its claims.
- VTT charged a 26Ah Donut Lab cell using CC/CV at 5C and 11C, reaching 80 in about 9.5 minutes with surface temperatures peaking at 63°C.
- Industry adoption could cut EV charging to a 5-minute stop, but VTT halted an 11C test at a 90°C cutoff and Donut Lab says shipments to Verge Motorcycles are due within weeks.
- Experts warn that the most extraordinary specifications remain unverified and the 400 Wh/kg energy-density claim remains untested while Donut Lab’s 100,000-cycle claim is unverified; Svolt Energy chairman Yang Hongxin called the specifications `scam` and experts said the combination defies known chemistry.

Yep, it’s fast: Donut Lab’s solid-state battery gets its first test result
Since announcing earlier this year that it was on the cusp of a major battery breakthrough, Finnish startup Donut Lab has faced a lot of questions, and plenty of skepticism, about its production-ready, solid-state battery. Could the company really make a fast-charging battery at scale while avoiding some of the theoretical production headaches that have stymied past efforts? Today, Donut Lab sought to dispel some of the doubts with the release o…
Donut Labs' battery managed to charge to 80 percent in 4.5 minutes in an independent VTT test. However, the whole is crucial, say battery experts.
Donut Labs Responds to Critics - CleanTechnica
There has been a frenzy of response to Donut Labs’ announcement of the world’s first solid-state battery. Donut Labs produced a response video to critics. The video says everyone jumped the shark, and independent testing is coming. It drops hints all over the place. It tells their strategy and why ... [continued] The post Donut Labs Responds to Critics appeared first on CleanTechnica.
Donut Lab announced on Monday that its miracle battery does indeed charge quickly. However, the latest research results were conducted with just one battery cell, the composition of which is also a mystery.
