Effect of La substitution on energy storage properties of (Bi0.2Na0.2Ca0.2Ba0.2Sr0.2)TiO3 lead‐free high‐entropy ceramics

“…27 In addition, the long-range ferroelectric order can be severely disrupted through La doping, which will contribute to the promotion of ergodicity degree and energy storage performance. [28][29][30][31] Zhang et al reported that the ergodic degree deepened with La content in a La-doped 0.93(Na 0.5 Bi 0.5 )TiO 3 -0.07Ba(Zr 0.055 Ti 0.945 )O 3 system, which resulted in "slimmer" P-E loops and enhanced η and W rec . 29 Yu et al added La to 0.78Na 0.5 Bi 0.5 TiO 3 -0.22K 0.5 Bi 0.5 TiO 3 ceramics and discovered that the ferroelectric order was largely disrupted by La doping and converted to an ergodic relaxation state.…”

“…synthesized lead‐free La‐substituted 0.72Na0.5Bi0.5TiO3‐0.28Sr0.7Bi0.2TiO3 and showed that La addition effectively decreased the grain size and generated a large E b , achieving the optimum W rec (1.2 J/cm 3 ) for 0.005La‐substituted ceramic under an E b of 90 kV/cm 27 . In addition, the long‐range ferroelectric order can be severely disrupted through La doping, which will contribute to the promotion of ergodicity degree and energy storage performance 28–31 .
