The specific capacity of 1D perovskite lithium-ion batteries is 763.0 mAh g −1 at low current charge and discharge rate of 150 mA g −1, which is twice that of the 3D perovskite CH 3 NH 3 PbBr 3 and 40% higher than that of the 2D perovskite (BA 2 MA n–1 Pb n Br 3n+1).
Our study opens up new directions for the applications of hybrid perovskites in energy storage devices. One-dimensional hybrid perovskite C 4 H 20 N 4 PbBr 6 based lithium-ion batteries have achieved a stable specific capacity of 598 mAh g −1 after 50 cycles, with good stability tested for up to 500 cycles.
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.
In various dimensions, low-dimensional metal halide perovskites have demonstrated better performance in lithium-ion batteries due to enhanced intercalation between different layers. Despite significant progress in perovskite-based electrodes, especially in terms of specific capacities, these materials face various challenges.
However, there are limited reports on the use of perovskite materials for energy storage applications in zinc-ion batteries. Zhuang et al. has demonstrated the use of bimetallic oxides (NiMnO 3) with perovskite structure as cathode material for ZIBs, which exhibited a capacity of 120 mAh/g at 1000 mA/g after 1000 cycles .
The capacity of the lithium-ion battery based on 2D structure perovskite at the first cycle is about 375 mAh g −1, which indicates that improving the intercalation ability could benefit the performance of lithium-ion batteries. Tathawadekar et al. found that lowering the dimensional was effective to improve the lithium storage.
One important trend to achieve PCEs >20% has been the usage of more complex perovskite compositions, ranging from double-cation (MAFA or CsFA) (7–9) and triple-cation (CsMAFA) to Rb-modified perovskites …
