摘要

Dielectric ceramics with high polarization and low sintering temperature are important for high-performance and low-cost multilayer ceramic capacitors (MLCCs). Herein, BiFeO₃ was added to a lead-free composition 0.48BaTiO₃-0.4Bi(Mg_0.5Hf_0.5)O₃-0.12SrTiO₃ to lower the sintering temperature and increase the polarization simultaneously. As a result, a low sintering temperature of 950 °C and high comprehensive energy storage properties with a recoverable energy density W_rec of 5.7 J/cm³ and an energy efficiency η of 92% at 450 kV/cm were achieved. Together with the good temperature stability and cycling stability of W_rec and η, the ceramics exhibit great potential in the energy storage MLCCs with low-cost Ag-Pd electrodes with a high Ag content.
