Dielectric capacitors possessing high power density and ultrashort discharge time are valuable for high-power energy storage applications. However, achieving high energy storage density remains challenging due to the limited breakdown strength of dielectric ceramics. In this study, inspired by the layered architecture of natural nacre and with the guidance of phase-field simulations, a strategy of constructing a nacre-like layered structure is proposed to improve the breakdown strength and energy storage density of the ceramics. This unique structure is formed by controlling the morphology and ordering of high-voltage-resistant fillers in a ceramic matrix. The (Pb
