Mechanism should be recognized to characterize them as battery or pseudocapacitive electrode. Effect of cation leaching on the oxygen vacancies, surface area and functioning of other metal cation should be identified. Creation of controlled oxygen vacancies using ex situ methods for the stabilization of perovskite oxide structure.
Perovskite materials have been an opportunity in the Li–ion battery technology. The Li–ion battery operates based on the reversible exchange of lithium ions between the positive and negative electrodes, throughout the cycles of charge (positive delithiation) and discharge (positive lithiation).
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.
