Although the lead based halide perovskite has been applied in the anode of the lithium battery, it is necessary to develop new lead-free perovskite anode materials because of its the instability and environmental unfriendliness.
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.
To eliminate the use of lead-based perovskites, Jaffe et al. initially reported extended Li + cycling in a metal chloride electrode based on lead-free (EDBE) [CuCl 4] perovskite as a cathode for LIBs. The results demonstrated over 200 cycles and an open-circuit voltage of 3.2 V.
To further enhance the stability of lead-free perovskites, all-inorganic lead-free perovskites have recently gotten considerable attention. In numerical simulation, the CsSnI 3 based perovskite solar cell has the highest power conversion efficiency of 28.97% among all the lead-free perovskite based devices.
As a result, a considerable amount of research is now focused on developing stable lead-free perovskites for LIBs. These lead-free perovskites exhibit complex crystal structures that are tolerant to defects and can accommodate inserted ions, making them promise for Li + storage.
Precisely, we focus on Li-ion batteries (LIBs), and their mechanism is explained in detail. Subsequently, we explore the integration of perovskites into LIBs. To date, among all types of rechargeable batteries, LIBs have emerged as the most efficient energy storage solution .
