Abstract:
Metal halide perovskites have rapidly emerged as a revolutionary frontier in materials science, catalyzing breakthroughs in energy storage technology. Originating as transformative entities in the field of solar cells, these perovskites have surpassed conventional boundaries. This comprehensive review embarks on a journey through the intriguing potentials of energy storage, driven by the exceptional properties of perovskite materials. We delve into three compelling facets of this evolving landscape: batteries, supercapacitors, and the seamless integration of solar cells with energy storage. In the realm of batteries, we introduce the utilization of perovskites, with a specific focus on both lead and lead-free halide perovskites for conciseness. Leveraging superior electrical properties such as high ionic conductivity (ranging from 10−3 to 10−4 Scm−1 for Li-ion) and diverse structural dimensions coupled with remarkable diffusion coefficients (2.68 × 10−8 cm2s−1 and 3.63 × 10−9 cm2s−1) for Chloride and Iodide-based halide perovskites, respectively, we explore the immense potential of perovskites as electrodes compared to other host materials such as layered oxide, carbon, etc., specifically for Al-ion, Zn-ion, and Li-ion batteries application, paving the way for the next generation of energy storage devices. In the domain of supercapacitors, we discuss the application of halide perovskites, highlighting both their advantages and limitations. We also provide a brief overview of the significant progress made in the supercapacitor domain using perovskite materials over the years. Additionally, we venture into unexplored territories, emphasizing the potential integration of solar cells and energy storage systems, delving into innovative concepts such as photo-accelerated capacitors/supercapacitors and photo-accelerated batteries. Importantly, we presented a detailed analysis of the impact of the perovskite composition on different energy storage applications. Ultimately, we outline the significant advantages, recognize the existing limitations, and stimulate imagination concerning the boundless future potential of halide perovskites in the energy storage domain, fostering a scientific and innovative perspective that contributes to the ongoing research and practical application of perovskite materials.
