Enhanced energy storage density of all-organic fluoropolymer composite dielectric via introducing crosslinked structure.

ABSTRACT: Polymer-based dielectrics have been attracted much attention to flexible energy storage devices due to their rapid charge-discharge rate, flexibility, lightness and compactness. Nevertheless, the energy storage performance of these dielectric polymers was limited by the weak dielectric breakdown properties. Crosslinked structure has been proven efficient to enhance breakdown strength (E _b) and charge-discharge efficiency (η) of polymer film capacitors. However, crosslinked networks usually lead to low electric displacement of dielectric capacitors, which greatly restrict their energy storage density (U _d). In this work, we present a tri-layered composite via layer-by-layer casting technology, where crosslinked polyvinylidene fluoride (c-PVD
