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.
The stable specific capacity is 2.36 times higher than that of the three-dimensional perovskite CH 3 NH 3 PbBr 3 (253.2 mAh g −1), and 1.6 times higher than that of the commercialized graphite electrode (372 mAh g −1).
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.
The properties of perovskite-type oxides that are relevant to batteries include energy storage. This book chapter describes the usage of perovskite-type oxides in batteries, starting from a brief description of the perovskite structure and production methods. Other properties of technological interest of perovskites are photocatalytic activity, magnetism, or pyro–ferro and piezoelectricity, catalysis.
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.
