On page 6658, H. Wang and co‐workers report a sandwich‐structured BaTiO 3 /poly(vinylidene fluoride) (PVDF) nanocomposite with an ultrahigh energy density of 18.8 J cm −3 . The electric field distribution and polarization in this structure can be optimized by adjusting the volume fraction of the ceramic fillers in different layers, resulting in a high breakdown strength and large dielectric polarization simultaneously.
