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_0.52Ti_0.48O₃/Al₂O₃/PbZr_0.52Ti_0.48O₃ 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.

结构-性能关系：相对的双异质结铁电绝缘体的高储能性能（Adv。Funct。Mater。10/2018）

李伟利，费卫东和他的同事们在编号1706211中设计了一种具有相反的双异质结铁电体-绝缘体-铁电体结构的介电电容器，用于储能。这种新颖的构造提高了PbZr _0.52 Ti _0.48 O ₃ / Al ₂ O ₃ / PbZr _0.52 Ti _0.48 O ₃异质结膜的电击穿强度和能量存储密度。通过调节退火温度，可实现高能量存储效率和线性磁滞回线。储能密度和效率都得到了显着提高。
