Abstract
A sandwich structure design strategy was presented in this work to optimize the polarization and electric breakdown strength of lead-free ceramics, resulting in superior energy storage properties (<italic>W</italic><sub>rec</sub> = 6.3 J cm<sup>−3</sup> and <italic>P</italic><sub>D</sub> = 215 MW cm<sup>−3</sup>).
