(0.74−x)(Na0.5Bi0.5)TiO3-xBaTiO3-0.26SrTiO3 (x=0∼0.1) (abbreviated as NBT-xBT-ST) lead-free ceramics were fabricated by a solid-state reaction method. The effect of Ba doping amount x on the structure and energy storage properties of NBT-xBT-ST ceramics were investigated. All the NBT-xBT-ST ceramics showed single perovskite structure with a pseudocubic phase. Ba doping effectively suppressed grain growth, in favor of forming small and uniform grains. The ceramics with a composition of x=0.04, an optimized energy storage density (γ=0.47J/cm3) and efficiency (η=48.67%), under an applied electric field of 50kV/cm, should be a candidate for solid-state compact pulsed power capacitor materials.
