Donut Lab’s ‘solid-state’ battery exposed as regular li-ion in damning investigation
A comprehensive investigation by battery researcher Ziroth, involving over 20 independent battery experts, has produced what amounts to definitive proof that Donut Lab’s “miracle” solid-state battery is actually a lithium-ion cell. The company raised approximately $25 million from over 1,300 mostly small investors based on claims that now appear to be false.
The investigation traces the battery technology back to a German company called CT Coatings, reveals a web of companies hiding behind aggressive NDAs, and presents electrochemical evidence — including voltage curves and cell expansion data — that conclusively identifies the tested cell as lithium-ion, not the revolutionary sodium-ion solid-state chemistry Donut Lab promised.

Watch a BYD electric sedan do a full tank turn in a hilariously tight space
A viral video racking up hundreds of thousands of views shows a BYD electric sedan performing a tank turn in an impossibly narrow space between barriers.
It’s a striking demonstration of what independent electric motors and smart torque vectoring can do in the real world — and a feature that US automakers have only promised.
China’s EV shift cut pollution enough to prevent 262,000 deaths
China’s rapid switch to electric and other new energy vehicles cut urban air pollution enough to prevent an estimated 262,000 premature deaths, according to a new peer-reviewed study published in Nature Health.
It’s some of the strongest real-world evidence yet that electrifying transportation delivers measurable public-health benefits, not just lower tailpipe emissions on paper.
The real reason why e-bike throttles have gotten worse
I’m going to say something that may make me sound old, but I just don’t care. E-bike throttles used to be better in the old days.
Not every e-bike throttle, of course. There have always been good ones and bad ones. But if you’ve been riding e-bikes for a decade or more, you’ve probably noticed the same trend I have.
