Donut Lab solid-state battery claims tested and proven as legitimate.

A recent test conducted by Finnish research institution VTT confirms that Donut Lab’s latest generation of solid-state batteries possess characteristics distinctly different from those of supercapacitors, thus ruling out speculation regarding its nature. According to the company, this latest test verifies that their advanced technology indeed enables practical battery functionality in a wide range of applications, rather than simply storing electrical energy through electrostatic double-layer capacitance.
