(D) discharged energy density and efficiency of pristine P(VDF-HFP) and PMMA, tri-layered PMMA/P(VDF-HFP) films and DE/PMMA/P(VDF-HFP) films. This means that if you have two identical capacitors in parallel, connected to the same source of voltage, the one with its interplate gap filled with a dielectric will contain more stored energy than the other that has its gap filled with a vacuum. A unit volume of dielectric stores an excess energy equal to $\frac 1 2 (K-1)\epsilon_0E^2$ other than what is stored by vacuum. J. The authors declare no conflict of interest. Chi, X.
