Realizing excellent energy storage performance and fatigue endurance in Sr0.7Sm0.2TiO3 modified 0.67BiFeO3-0.33BaTiO3 lead-free relaxor ceramics

Synergistic modulation of ferroelectric polarization and relaxor behavior of Sr2NaNb5O15‐based tungsten bronze ceramic

“…Meanwhile, the corresponding C D and P D respectively rise up to 863.06 A/cm 2 and 94.94 MW/cm 3 . A comparison of the charge‐discharge properties is presented in Figure 6(E) 24,39,56,70–75 . Obviously, the C D and P D obtained in the SBNNT‐0.15 ceramic are higher than that of many reported lead‐free dielectric ceramics, demonstrating the remarkable capacity for high‐power pulse capacitors.…”

Achieving outstanding temperature and frequency stability in NaNbO3-modified (Ba0.94Li0.02La0.04)(Mg0.04Ti0.96)O3 pulse energy storage ceramics

“…7(b) demonstrates the comparison of the energy-storage properties of the 0.85BLLMT–0.15NN sample with other lead-free ceramics. 7,11–13,19–21,29–34 The 0.85BLLMT–0.15NN sample has dual priority values of W rec and η than other lead-free ceramics, which is caused by the high BDS value, reduced domain size, and multiphase coexistence in the system. Such an improvement is correlated with the O and R phases that can provide more polarization orientation than the T phase, enhancing the P max value.…”

High energy storage density achieved in BNT‐based ferroelectric translucent ceramics under low electric fields

“…A comparison of W rec between the 0.9BNT-0.1BZT:0.6Er 3+ ceramic in this work and previously published works for other lead-free ferroelectric ceramics at a lower electric field is shown in Figure 8. 13,41,[53][54][55][56][57][58][59][60][61][62][63][64][65][66][67][68][69][70][71][72] Table 2 presents another comparison of energy storage ability (P max and W rec /E). 11,34,63,[73][74][75][76][77] The results show that this work has reached an advanced level with a W rec of 2.95 J/cm 3 and W rec /E of 155.26 J/(kVˑm 2 ) at a low electric field (190 kV/cm).…”
