Structure, dielectric and relaxor properties of Sr0.7Bi0.2TiO3K0.5Bi0.5TiO3 lead-free ceramics for energy storage applications

NaNbO3‐(Bi0.5Li0.5)TiO3 Lead‐Free Relaxor Ferroelectric Capacitors with Superior Energy‐Storage Performances via Multiple Synergistic Design

“…All of these might require an in-depth 32BLT ceramics and other recently reported bulk ceramics. [2][3][4][5][31][32][33][56][57][58][59][60][61][62] The red star and the purple star represent the energy-storage properties of 0.68NN-0.32BLT and 0.68NN-0.32BT ceramics, respectively. The P-E loops for c) pure NN and d) 0.68NN-0.32BT/BLT ceramics measured under their E test-max at 10 Hz; e) a comparison of E test-max , P max , W rec , and η values between pure NN and 0.68NN-0.32BT/BLT ceramics.…”

Achieving ultrahigh energy-storage capability in PbZrO3-based antiferroelectric capacitors based on optimization of property parameters

“…Thus, an optimal energy density is closely associated with BDS, which can be understood intuitively by the Weibull distribution functions. 49,50 As shown in Fig. 3(c), all compositions are tted well in the Weibull distribution, and the high shape parameter b (>20) indicates a smaller distribution range of the tested data.…”

“…(c) A comparison of the temperature-dependent W rec between this work and other energy-storage ceramics. 18,19,29,37,49,50,54,57 (d) P-E loops of the PLSZT5 ceramic from 25 to 120 C at 420 kV cm; (e) corresponding W tot , W rec , W loss and h at various temperatures. (f) A comparison of the frequency-dependent W rec between this work and other energy-storage ceramics.…”

“…63 Differently, the resistance-inductance-capacitance (RLC) circuit is oen used to judge the actual discharge process of dielectric capacitors due to fast discharge speed in microseconds, even nanoseconds. 49,64 Thus, pulsed discharge measurements of the PLSZT5 ceramic under different conditions were conducted to further evaluate the energy-storage capability in actual applications.
