Abstract

High recoverable energy density (Wrec ∼ 2.1 J/cm3) was obtained in (0.7 – x)BiFeO3-0.3BaTiO3-xBi(Zn2/3Nb1/3)O3 + 0.1 wt % Mn2O3 (BF-BT-xBZN, x = 0.05) lead-free ceramics at <200 kV/cm. Fast discharge speeds (<0.5 μs), low leakage (∼10–7 A/cm2), and small temperature variation in Wrec (∼25% from 23 t...
