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. [Display omitted] •The supercapacitor (SC) applications of Perovskite oxides and metal halides were reviewed.•Electrochemical performance of single and double perovskite oxides was discussed.•Doping of foreign atoms/their composite structure can improve the storage performance.•Metal halide perovskites-based thin film supercapacitor's performances were evaluated.•Challenges/scope of perovskite materials in SC development technology were summarized.
