Abstract
Abstract Dielectric capacitors with ultrahigh power density have emerged as promising candidates for essential energy storage components in electronic and electrical systems. They enable enhanced integration, miniaturization, and lightweight design. However, the development of dielectric materials for cutting-edge energy storage applications has been significantly limited by their low recoverable energy storage density ( W rec ) and energy efficiency ( η ), especially at moderate electric fields. In this study, we fabricated 0.85K 0.5 Na 0.5 NbO 3 -0.15Sr 0.7 Nd 0.2 ZrO 3 ceramics with an outstanding energy storage performance ( W rec ~ 7 J cm − 3 , η ~ 92% at 500 kV cm − 1 ; W rec ~ 14 J cm − 3 , η ~ 89% at…
