Article Synopsis
- Reversible phase transitions in antiferroelectric perovskite oxides are crucial for developing high-energy storage materials for green technology.
- By modifying local structures and defect chemistry in NaNbO-based antiferroelectrics, researchers achieved significant improvements in energy storage and reversibility.
- Techniques like X-ray diffraction and electron microscopy were used to analyze these materials, leading to a tenfold increase in energy storage density and a high efficiency of 90%.
Lead zirconate (PbZrO, PZ) is a prototype antiferroelectric (AFE) oxide from which state-of-the-art energy storage materials are derived by chemical substitutions. A thorough understanding of the structure-property relationships of PZ-based materials is essential for both performance improvement and the design of more environmentally friendly replacements. (PbBa)ZrO (PBZ) can serve as a model system for studying the effect of A-site substitution in the perovskite lattice, with barium destabilizing the AFE state.
