Lead-free single-phase perovskite BaTiO3-Bi(Al0.5Sc0.5)O3 ceramics as novel high performance BaTiO3-based energy storage ceramics were synthesized by a solid-state reaction method. Effect of BAS content on the structure, dielectric properties, energy storage of (1-x) BT-xBAS ceramics was investigated. The (1-x)BT-xBAS solid solution transforms from tetragonal (x≤0.05) to cubic (x≥0.1), but is still based on the tetragonal. The Tm moves toward a low temperature range, and the dielectric peak broadens with the BAS content increases, exhibiting a dispersive dielectric behavior with respect to frequency. The long-range ferroelectric order of ceramics is destroyed by BAS. Also, the phase transition of BT-xBAS ceramics is from a typical ferroelectric phase to a relaxor phase. The phenomena both indicate that the BT-BAS ceramics could have the excellent characteristics of relaxor ferroelectrics. The 0.85BT-0.15BAS ceramics show a good temperature stability, and the diffusion coefficient γ is 1.97. There are an energy storage density of 0.684 J·cm-3 and an energy efficiency of 95% in an electric field of about 105 kV/cm.
