Figure 14. Enhanced ESP through grain-scale composite ceramic design. (A) Incorporation of bismuth layer-structured BaBi₂Nb₂O₂ into perovskite Sr_0.6(Na_0.5Bi_0.5)_0.4TiO₃ ceramic via traditional solid-state synthesis to improve overall ESP. This figure is quoted with permission from Wu et al.^[128]; (B) Embedding high-breakdown-strength plate-like pyrochlore phase within high-polarization perovskite matrix to boost ES in BNT-based ceramics. This figure is quoted with permission from Wang et al.^[129]; (C) Superior ESP in BT-based RFE ceramics with reconstructed microstructure featuring elongated rod-shaped and polygonal perovskite grains. This figure is quoted with permission from Yin et al.^[130]. ESP: Energy storage performance; BNT: (Bi_0.5Na_0.5)TiO₃; ES: energy storage; RFE: relaxor ferroelectric; BT: BaTiO₃; BMT: Bi(Mg_1/2Ti_1/2)O₃.
