摘　　要：Multilayer dielectric capacitors were fabricated from nanocomposite precursor comprised of BaTiO_(3)@TiO_(2) core–shell nanosized particles and poly(vinylidene fluoride–hexafluoropropylene)(P(VDF–HFP))polymer matrix(20 vol%).The multilayer capacitors showed very high discharge speed and high discharged energy density of around 2.5 J/cm^(3) at its breakdown field(~166 MV/m).The energy density of the nanocomposite multilayer capacitors was substantially higher than the energy density of commercially used power capacitors.Low cost,flexible structure,high discharge rate and energy density suggest that the nanocomposite multilayer capacitors are promising for energy storage applications in many power devices and systems.
