In an initial investigation , iodide- and bromide-based perovskites (CH 3 NH 3 PbI 3 and CH 3 NH 3 PbBr 3) were reported as active materials for Li-ion batteries with reversible charge-discharge capacities.
Moreover, perovskites can be a potential material for the electrolytes to improve the stability of batteries. Additionally, with an aim towards a sustainable future, lead-free perovskites have also emerged as an important material for battery applications as seen above.
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.
As several works have manifested that halide perovskites are conceivable for battery applications, it is believed that there is still room for halide perovskites batteries to go beyond for further performance improvement. 5.2. Supercapacitors
The existence of these vacancies thinning the perovskite electrode layer provides the voids or porous arrangement of the perovskite which enhances the perovskite conductivity, facilitates the accessibility of the electrolyte's ions, and accelerates the ionic migration throughout the layer.
The number of layers and perovskite layering in 2D-based perovskites, especially quasi-2D perovskites, play a vital role in determining the electrochemical performance of energy storage systems [52, 115], as shown in Fig. 9, reported a 2D perovskite with a crystal structure of (BA) 2 (MA) 3 Pb 4 Br 13, featuring an interplanar distance of 20.7 Å.
