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.
