“…Shifting from 3D to the lower dimension, not only 2D but also 1D or 0D (or even the ultimate molecular dimension) could be effective to enhance the energy storage performance. The dimensional tailoring including the 3D/2D mixing [233][234][235][236][237][238][239][240] offers combined excellent light-to-electricity conversion efficiency and stability; this strategy could be examined to facilitate the lithium intercalation in halide perovskites. More crystallographic and theoretical works should be carried out to understand the layered structure of halide perovskites, including the role the π ···π stacking and van der Waals interactions are playing to stabilize the overall surface structure and the charge carrier transport.…”

Halide perovskites, traditionally a solar-cell material that exhibits superior energy conversion properties, have recently been deployed in energy storage systems such as lithium-ion batteries and photorechargeable batteries. Here, recent progress in halide perovskite-based energy storage systems is presented, focusing on halide perovskite lithium-ion batteries and halide perovskite photorechargeable batteries. Halide-perovskitebased supercapacitors and photosupercapacitors are also discussed. The photorechargeable batteries and photorechargeable supercapacitors employ solar energy to photocharge the battery; this saves energy and improves device portability. These lightweight, integrated halide perovskite-based systems, which are pertinent to electric vehicles and portable electronic devices, are reviewed in detail. Suggestions on future research into the design of halide-perovskite-based energy storage materials are also given. This review provides a foundation for the development of integrated lightweight energy conversion and storage materials.

resistance against thermal-treatment compared to organic-inorganic hybrid lead halide perovskites (MAPbX 3 and FAPbX 3), due to the high thermal decomposition temperature of inorganic cations, thus drawing much attention. Owing to their impressive features, all-inorganic lead halide perovskites have been greatly useful in photovoltaic and optoelectronic applications, including solar cells, light-emitting diodes (LEDs), lasers, photodetectors and photocatalysis. [5-17] The conspicuous achievements in CsPbX 3 provoke the rapid development of its derivatives, Cs 4 PbX 6 and CsPb 2 X 5. These Cs x Pb y X z materials are composed of the same element compositions and [PbX 6 ] 4− unit cells. However, they possess completely different connectivity characters of [PbX 6 ] 4− octahedrons. CsPbX 3 is classified as a type of 3D perovskite, because [PbX 6 ] 4− octahedra are corner-shared along all three axes, while CsPb 2 X 5 has a sandwich-like arrangement with Cs + cations in between PbX 2 crystallographic planes, which can be regarded as a 2D phase. In Cs 4 PbX 6 , disconnected [PbBr 6 ] 4− octahedra are completely decoupled by Cs + cations. Among these three structures, CsPb 2 X 5 and Cs 4 PbX 6 , with dimensional-network less than 3 are referred to as lowdimensional-networked cesium lead halide perovskites. Besides the connectivity, these structures can be understood from a confinement perspective. CsPbX 3 is not confined in any dimension such that it can be considered as a 3D networked semiconductor. CsPb 2 X 5 and Cs 4 PbX 6 are confined in one dimension and all three dimensions, hence the name 2D and 0D structures, respectively. [18,19] In CsPb 2 X 5 and Cs 4 PbX 6 , the excitons cannot dissociate easily within all dimensions; instead, they are confined in the PbX 2 planes and individual [PbX 6 ] 4− units, respectively, resulting in larger bandgaps compared to the traditional ABX 3 phase. Figure 1 illustrates these three structures with different dimensions. Until now, comprehensive accounts of these Cs x Pb y X z materials have been made. However, most recent research focuses on CsPbX 3 , which has excellent optical properties and promising potential in various applications. Its derivatives, CsPb 2 X 5 and Cs 4 PbX 6 have achieved tremendous progress but are still far behind that of CsPbX 3. Many problems still seriously limit the rapid development of these low-dimensional-networked perovskites, a typical one being the debate on the origin of their luminescence. In this Review article, we focus on Cs 4 PbX 6 and CsPb 2 X 5 , and attempt to unveil their features, potential in All-inorganic cesium lead halide perovskites have emerged as promising optoelectronic materials with excellent photophysical properties and great potential in a variety of applications. In parallel with the most investigated CsPbX 3 , its derivates, Cs 4 PbX 6 and CsPb 2 X 5 , with low-dimensional-networked structures have also attracted great attention. In this review, recent advancements on the low-dimensional-networked cesium lead halide perovs...

“…[52][53][54][55] For example, the dimensionally tailored 2D/3D halide perovskite materials exhibit excellent stability and optoelectronic performance. [56][57][58][59] In addition, it is viable to employ the solid electrolyte to substitute the water-based solution to minimize the degradation. [60][61][62][63][64] Second, a small voltage is produced by the CH 3 NH 3 PbI 3 /LiFePO 4 system; this is ascribed to the fact that the halide perovskite CH 3 NH 3 PbI 3 is traditionally considered as an anode material for the lithium-ion battery.…”

The photo-responsive capability of lithium battery materials is a prerequisite to realize new-generation lightweight photo-rechargeable batteries. However, the photo-charging property is not available for common battery electrode materials such as LiFePO 4. In this manuscript, we provide evidence that the halide perovskite material CH 3 NH 3 PbI 3 is able to activate the photo-charging properties of the lithium-ion battery electrode material LiFePO 4. The photoelectrochemical measurement demonstrates that the photo-responsive property of the CH 3 NH 3 PbI 3 /LiFePO 4 composite is significantly improved; the photo-induced signals are neither observed in the individual halide perovskite nor the lithium battery material tested under the same condition.
