In article number 1706211 , Weili Li, Weidong Fei, and co‐workers design a dielectric capacitor with opposite double‐heterojunction ferroelectrics‐insulator‐ferroelectrics configuration for energy storage. This novel configuration enhances the electric breakdown strength and energy storage density of PbZr 0.52 Ti 0.48 O 3 /Al 2 O 3 /PbZr 0.52 Ti 0.48 O 3 heterojunction films. High energy storage efficiency and linear hysteresis loops are achieved by regulating the annealing temperature. Both, energy storage density and efficiency have been improved significantly.
