The Electrostatic Energy-Density Ceiling of Dielectric Capacitors, Recounted: Weibull Quantiles, Area and Thickness Scaling, and the Inflation in Headline Values

Stored energy densities for dielectric capacitors are recounted for BOPP, PVDF, P(VDF-TrFE-CFE), a BaTiO3-based ceramic, an aluminoborosilicate glass, and PEI at 150 C, using high-field effective permittivities, 1% Weibull quantiles, and area and thickness scaling to a 100 cm2 device. Defensible values are 3.5 to 352.2 times smaller than conventional headline combinations (median 12.2). All numbers are computed by the deposited script from stated literature inputs.
