Strain-electric field (S–E) loops confirm piezoelectric behavior.
Room temperature (300 K) charge curve and discharge curve energy densities [(Ed)c 0.35 (before aging) 0.39 J/cm3 (aged)], [(Ed)d 0.20 (before aging) 0.24 J/cm3 (aged)], respectively, at a maximum electric field 50 kV/cm.
The bulk BCT materials have shown interesting energy densities with good energy storage efficiency (58% before aging, 61% after aging) suggesting they might be strong candidates for high energy density capacitor applications.
