اطلاعات بیشترPerovskite, widely used in solar cells, has also been proven to be potential candidate for effective energy storage material. Recent progress indicates the promise of perovskite for battery applications, however, the specific capacity of the resulting lithium-ion batteries must be further increased.
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).
Ahmad et al. demonstrated the use of 2D lead-based perovskites, namely, (C 6 H 9 C 2 H 4 NH 3) 2 PbI 4, as a photo-active electrode material in a lithium-ion battery [Figs. 4 (a) and 4 (b)]. 90 The battery with the iodide perovskite showed a specific capacity up to 100 mAh g −1 at 30 mA g −1.
Lead-free perovskite halides can also be used for electrodes, but this research is still in its early stages. Pb-based perovskite halides in Li-ion batteries. Lead-based halide perovskites, as previously indicated, have exceptional capacity to operate as electrodes in lithium batteries.
It is worth noticing that after the current density dropped from 1500 to 150 mA g −1, the stable specific capacity further restored to 595.6 mAh g −1, which was 86% of the initial stable capacity, showing the potential of perovskite-based lithium-ion batteries for fast charge and discharge.
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.
