Skepticism grows around Donut Lab’s “impossible” battery as experts debate capacitor-like behavior and scarce independent test data.

Earlier this year, Finnish startup Donut Lab grabbed headlines after claiming it had developed the first production-ready solid-state EV battery capable of charging in about five minutes. The ...

The startup's third test evaluates whether its solid-state battery is actually a supercapacitor. Here's what the results say.

Abstract: In this paper, a bended differential transmission line using the asymmetric coupled line (ACL) with surface mount device (SMD) capacitor is proposed to suppress the common-mode noise. The ...

Abstract: This paper presents both theoretical and numerical analyses of the piezoelectric and dielectric responses of a highly idealized film-on-substrate system, namely, a polarized ferroelectric ...
