VTT Report on Donut Lab’s Solid-State Battery is a Nothingburger

A report by VTT on Donut Lab's Solid-State Battery suggests it may be indistinguishable from a traditional NMC cell, with key performance parameters like energy density and charge cycle life not clearly demonstrated. The report reveals energy capacity results at different charge rates, but crucial data like cell dimensions and mass are missing, raising doubts about the claimed 400 Wh/kg energy density. Despite some positive results, the report is criticized for lacking essential measurements and conclusive evidence, leading to skepticism about the battery's true capabilities.
