“…Thus, it is urgent to seek a feasible method to improve the discharge performance of batteries or explore a self‐powered system. In this regard, a promising solution is to design an integrated system by combining energy storage modules with environmental responsive modules that can harvest energy from the ambient surroundings such as solar, [ 18–25 ] thermal, [ 26–29 ] and wind energy, [ 30 ] or mechanical energy resulted from human movements etc. [ 31–34 ] On one hand, such integrated system could enable the direct compensation of energy consumption for energy storage units and realize self‐charging without extra electricity input.…”

Aqueous rechargeable Zinc (Zn)–polymer batteries are promising alternatives to prevalent Li‐ion cells in terms of cost, safety, and rate capability but they suffer from limited specific capacity in addition to poor environmental adaptability. Herein, air and light are successfully utilized from external environments in single near‐neutral two‐electrode Zn batteries to enable remarkably improved electrochemical performance, fast self‐charging, and switchable multimode‐operation from Zn–polymer to Zn–air cells. This system is enabled by a well‐designed polyaniline‐nanorod‐array based “all‐in‐one” cathode combining reversible redox capability, oxygen reduction activity, and photothermal‐responsiveness. The initiative design allows perfect integration of multiple energy harvesting from ambient “air” and light, energy conversion, and storage in one single cathode. Thus, it can act as an efficient light‐assisted electrically‐rechargeable Zn–polymer cell featuring the highest specific capacity of 430.0 mAh g−1 among all existing polymer cathodes. Without external power sources, it can be self‐charged to deliver a high discharging capacity of 363.1 mAh g−1 by concurrently harvesting chemical energy from air and light energy for only 20 min. It can also switch to a light‐responsive Zn–air battery mode to surmount the output capacity limit of Zn–polymer battery mode for continued electricity supply.

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.

Free-standing TiO2 nanotube (NT) electrodes have attracted much attention for application in solid- or quasi-solid-state dye-sensitized solar cells (DSSCs) because of their suitable pore structure for the infiltration of solid electrolytes. However, few studies have been performed on the relationship between nanostructures of these NT electrodes and the photovoltaic properties of the solid- or quasi-solid-state DSSCs. Here, we prepare vertically aligned and highly ordered TiO2 NT electrodes via a two-step anodization method for application in quasi-solid-state DSSCs that employs a polymer gel electrolyte. The length of NT arrays is controlled in the range of 10–42 μm by varying the anodization time, and the correlation between NT length and the photovoltaic properties of quasi-solid-state DSSCs is investigated. As the NT length increases, the roughness factor of the electrode is enlarged, leading to the higher dye-loading; however, photovoltage is gradually decreased, resulting in an optimized conversion efficiency at the NT length of 18.5 μm. Electrochemical impedance spectroscopy (EIS) analysis reveals that the decrease in photovoltage for longer NT arrays is mainly attributed to the increased electron recombination rate with redox couples in the polymer gel electrolyte.
