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.

Owing to the advantages of high power density, fast charge/discharge rates, as well as long lifetime, micro‐supercapacitors have drawn much attention for their potential application in miniaturized electronics. Great progress has been made in recent years. On the one hand, many efforts have been devoted to the design and fabrication of high‐performance miniaturized supercapacitors. On the other hand, integration of micro‐supercapacitors with multiple functional materials and devices has emerged with the development of portable and wearable microelectronics. This review first discusses the recent progress of fabrication methods and strategies in the micro‐supercapacitor field. The recent reports on integration of micro‐supercapacitors with smart functions, for instance, self‐charging, self‐protection, electrochromism, self‐healing, sensing, stretchability, as well as photo‐switchimg, are summarized. The perspectives on micro‐fabrication strategies and integrated multifunctionalities of smart micro‐supercapacitors are provided at the end.

Photopowered energy systems (PPESs), which simultaneously achieve power conversion and energy storage, are one of the most promising auxiliaries to fulfill the giant and diversified power demand in modern society. Devices with a low cost, wearable, compact structure and the potential to add a variety of features (such as photochromic, flexible, textile, and wearable) have received extensive research attention. Photo‐supercapacitors are becoming one of the most extensively researched PPESs due to their ease of fabrication, mitigation of solar irradiation discontinuities, and the promotion of renewable energy utilization, and these devices have been fabricated with different combinations of photovoltage devices and energy‐storage technologies. This review summarizes the development of photo‐supercapacitors that integrate third‐generation solar cells and supercapacitors, with a focus on materials alignment, performance, structure design, and application. Finally, current challenges, possible solutions, and future perspectives are discussed.
