Towards high-performance perovskite-based supercapacitors: A review of recent research developments

As we shift towards renewable energy sources, it’s more and more momentous to raise the efficiency and storage abilities of energy systems. Supercapacitors are especially valuable due to their capacity for delivering high power with fast charge and discharge cycles, making them perfect for energy storage applications. The introduction of nanomaterials in supercapacitor design has significantly boosted performance, resulting in increased surface area and improved electrical conductivity. Perovskites represent a unique category of materials with versatile structures and remarkable electrical properties, indicating promising possibilities for future supercapacitor technologies. Their capacity to facilitate ion transport and enhance electrochemical efficiency has the potential to revolutionize energy storage solutions. Recent studies on perovskite-based supercapacitors indicate their ability to provide elevated energy densities while maintaining rapid charge capabilities. This overview underscores the transformative role of perovskite materials in advancing supercapacitor technology, which could ultimately lead to more efficient energy systems and support sustainable energy initiatives. This review paper delves into the properties and physicochemical characteristics of ABO₃-type perovskite oxides, offering a comprehensive understanding of their potential applications. We explore various preparation methods, structural designs, and strategies aimed at enhancing the electrochemical presentation of contemporary perovskite oxides for supercapacitor development. We also emphasize the latest developments in supercapacitors that utilize perovskite materials. The last part discusses the ongoing challenges to this extent and advises possible avenues for future research.
