Improved energy-storage performance of (1–x)[(Bi0.5Na0.5)0.94Ba0.06]0.98La0.02TiO3–xBi(Mg0.5Zr0.5)O3 ceramics

Superior energy storage properties in lead-free NaNbO3-based relaxor antiferroelectric ceramics via a combined optimization strategy

“…Generally, introducing the low tolerance factor (o0.9671) dopants is an effective way to stabilize the AFE phase. [24][25][26] When the contents of these dopants are small, the AFE P phase plays a dominant role at room temperature. Zhang et al reported an ESP with a W total = 4.26 J cm À3 and Z of 48.6% in (1 À x)NaNbO 3 -xBi 2/3 HfO 3 ceramics with a typical AFE P phase.…”
