Multiscale reconfiguration induced highly saturated poling in lead-free piezoceramics for giant energy conversion.

ABSTRACT: The development of high-performance lead-free K_0.5Na_0.5NbO₃-based piezoceramics for replacing commercial lead-containing counterparts is crucial for achieving environmentally sustainable society. Although the proposed new phase boundaries (NPB) can effectively improve the piezoelectricity of KNN-based ceramics, the difficulty of achieving saturated poling and the underlying multiscale structures resolution of their complex microstructures are urgent issues. Here, we employ a medium entropy strategy to design NPB and utilize texture engineering to induce crystal orientation. The developed K_0.5Na_0.5NbO₃-based ceramics enjoys both prominent piezoelectric performance and satisfactory Curie temperature, thus exhibiting an ultrahi
