TL;DR: It is demonstrated that a very high energy density with fast discharge speed and low loss can be obtained in defect-modified poly(vinylidene fluoride) polymers by combining nonpolar and polar molecular structural changes of the polymer with the proper dielectric constants.

TL;DR: Aromatic polyurea thin films were developed through vapor phase deposition, exhibiting relatively high dielectric constant, low loss, high breakdown field (>800 MV/m) and consequently high energy density (>12 J/cm3) as mentioned in this paper.

TL;DR: In this paper, the electrical breakdown of a polar fluoropolymer, poly(vinylidene fluoride-hexafluoropropylene) which exhibits an exceptionally high discharged electrical energy density (>25 J/cm3), was investigated.

TL;DR: In this paper, the authors investigated the dielectric and discharge behavior of polyvinylidene fluoride-based copolymer film capacitors and found that the discharge energy density decreases with frequency and the discharged energy density is also reduced at shorted discharge time.

TL;DR: In this paper, the relaxor ferroelectric polymer-poly(vinylidene fluoride/trifluoroethylene/chlorofluoro methylene) terpolymer for energy storage capacitors was investigated and it was found that the high dielectric constant (>50 at 1 kHz) and high reversible polarization in the terpolymers lead to high electric energy density ~ 10 J/cm3, achieved under an electric field of more than 350 MV/m.
