Perovskite materials belong to a class of crystalline compounds characterized by a specific crystal structure called the perovskite structure. The general chemical formula for perovskite compounds is ABX 3, where A and B represent different cations, and X represents an anion.
Moreover, perovskite materials have shown potential for solar-active electrode applications for integrating solar cells and batteries into a single device. However, there are significant challenges in applying perovskites in LIBs and solar-rechargeable batteries.
Perovskite-type batteries are linked to numerous reports on the usage of perovskite-type oxides, particularly in the context of the metal–air technology. In this battery type, oxidation of the metal occurs at the anode, while an oxygen reduction reaction happens at the air-breathing cathode during discharge.
