Donut Lab Battery Isn't NMC, Contrary to Ziroth's Claim
A viral misidentification of Donut Lab's battery chemistry is corrected by visual evidence.
A recent claim by Ziroth that Donut Lab's battery uses NMC chemistry has been challenged by CleanTechnica. The rebuttal hinges on a simple visual clue: NMC batteries tend to swell, giving them a puffed, pillow-like appearance. Donut Lab's battery, by contrast, is flat and rectangular, resembling a Pop-Tart.
The evidence comes from a video of an NMC battery placed in a bath, which clearly shows the characteristic swelling. CleanTechnica argues that this shape difference is definitive, and that Ziroth's identification is mistaken. The article does not specify what chemistry Donut Lab actually uses, only that it is not NMC.
This correction matters because battery chemistry affects performance, safety, and cost. Mislabeling a battery's type could mislead investors, engineers, or consumers. Since only one source is available, there is no conflicting view to compare, but the visual argument is straightforward and based on observable behavior.
