What’s going on with Donut Lab?Finnish startup Donut Lab has made extraordinary claims about its new solid-state battery technology, promising rapid charging, extreme longevity, and high energy density using common materials. However, the company has faced significant skepticism from industry experts and the public due to a lack of verifiable proof and what appears to be misdirection in its demonstrations. Despite releasing test results conducted by VTT Finland, the data has been scrutinized, with many pointing out discrepancies between the promised performance and the observed outcomes, leading to ongoing debate about the legitimacy of Donut Lab's claims.
