High Energy Storage Density and Large Strain in Bi(Zn2/3Nb1/3)O3-Doped BiFeO3–BaTiO3 Ceramics

High recoverable energy density ( W rec ∼ 2.1 J/cm 3 ) was obtained in (0.7 – x )BiFeO 3 -0.3BaTiO 3 - x Bi(Zn 2/3 Nb 1/3 )O 3 + 0.1 wt % Mn 2 O 3 (BF-BT- x BZN, x = 0.05) lead-free ceramics at <200 kV/cm. Fast discharge speeds (<0.5 μs), low leakage (∼10 –7 A/cm 2 ), and small temperature variation... View More
