Abstract
High-temperature BaTiO3-based ceramic capacitors have broad application prospects in energy storage devices. However, energy density and efficiency of BaTiO3-based ceramic capacitors are bottleneck challenges that limit the applications of ceramic capacitors in the vast of industrial applications. To address this issue, it needs to design novel BaTiO3-based ceramics to elevate the breakdown strength, energy density and efficiency of capacitors. Here, high performance BaTiO3-based ceramics with breakdown strength of 290 kV cm−1, discharge energy density is more than 2.4 J cm−3, energy storage efficiency is achieve 91.5% are achieved in novel ternary system 0.88BaTiO3-0.12(1-x)Bi(Li0.5Nb0.5)O3-0.12xBi(Mg0.5Ti0.5)O3 (BT-BLN-BMT) (0.2 ≤ x ≤ 0.8) lead-free ceramic. Moreover, 0.88BT-0.12(1-x)BLN-0.12xBMT (x = 0.6) multilayer ceramics capacitors effectively increased breakdown strength and energy density values are more than 500 kV cm−1 and 4.42 J cm−3, improved by 488% and 1373% compared with only 85 kV cm−1 and 0.3 J cm−3 for the pure BaTiO3. It maintains high thermal stability in the temperature range from 25 °C to 150 °C. All these results have clearly collaborated the promising future of this novel BaTiO3-based ceramics in energy storage applications in the future.
