Achieving ultrahigh energy storage performance of PBLZST …
In addition, low interfacial polarization also leads to decreased dielectric properties (as shown in Fig. 3 (b)) and low P max, limiting the improvement of energy storage density [40], [41]. Notably, the P max at x = 0.3 is higher than that at x = 0.15, attributed to the higher E b of the S3 sample, which causes it to reach polarization saturation.
