Superior energy storage performance in (Bi0.5Na0.5)TiO3-based lead-free relaxor ferroelectrics for dielectric capacitor application via multiscale optimization design

“…2(i). 11,15,19,30,35,40,41,43,54–95 More strikingly, the combined high W rec and ultrahigh η in the BNT-BAT-0.4CT ceramics designed by the above multiscale optimization strategy are competitive with those of the state-of-the-art lead-free AFE ceramics ( W rec of 6.3 J cm −3 and η of 90%), 19 showing great prospects in the field of environment-friendly energy-storage capacitor applications.…”

Synergy of a Stabilized Antiferroelectric Phase and Domain Engineering Boosting the Energy Storage Performance of NaNbO3-Based Relaxor Antiferroelectric Ceramics

“…From an application viewpoint, a fast discharge rate and high power density are also essential for high-power energy storage applications. The underdamped discharge waveforms and the corresponding changes in the first current peak ( I max ), current density and power density ­(where E is the electric field strength and S is the electrode area) with respect to the electric field are shown in Figure a,b, respectively. I max, C D , and P D increase linearly as the electric field strength increases and eventually rise to 27.7 A, 883.2 A/cm 2 , and 114.8 MW/cm 3 at 260 kV/cm, respectively.…”
