Perovskites: A new generation electrode materials for storage applications

Since the last decades, perovskite structures are getting considerable attention in various electronics applications. Their controllable physico-chemical properties and structural advantages have been widely explored in energy storage applications. This review discusses the recent applications and scope of perovskite structures in supercapacitors using oxide, fluoride and halide perovskite materials. The review provides details of different perovskite structures such as single and double perovskites, and strategies for modulating the electrochemical performance of these materials like composite structure, elemental doping, tuning morphologies, crystallinity and surface defect engineering for improving oxygen vacancies.
