Abstract Dielectric materials have drawn increasing attention due to their high power density and fast charge-discharge speed. Although satisfactory energy storage performance has been achieved in lead-based ceramics, the exploration of suitable lead-free substitutions is highly desired since the rising environmental concerns caused by lead-based compounds. Herein, we demonstrate that a giant recoverable energy density of 7.01 J cm−3 together with high energy efficiency under 476 kV cm−1, as well as impressive frequency stability (maximum variation of recoverable energy density
