Dielectric and Ferroelectric Properties of SrTiO3–Bi0.5Na0.5TiO3–BaAl0.5Nb0.5O3 Lead-Free Ceramics for High-Energy-Storage Applications

A series of (1 − x)ST−x(BNT−BAN) ceramics were successfully fabricated. Pure ST possesses low Pmax, while the value of Pmax can be enhanced substantially with the introduction of BNT−BAN, which is beneficial to obtaining high W and high Wrec. Excellent energy-storage properties with a W of 2.46 J/cm3 and a Wrec of 1.89 J/cm3 can be achieved in the composition of 0.5ST−0.5(BNT−BAN). Therefore, (1 − x)ST−x(BNT−BAN) ceramics are promising lead-free materials for high-energy-storage applications.
