“…Various energy conversion materials have been devised to harvest the solar energy, which is considered to the clean and inexhaustible. [1][2][3][4][5][6][7] In the meantime, various energy storage materials have been devised to supply energy for electric vehicles and portable electronic devices that are pollution free. The coordinated development of the energy conversion and energy storage materials offers an effective approach for energy sustainable cities.…”

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.

“…In the 2000s, different types of PRB have been investigated: an electrochemical photovoltaic cell such as a dye-sensitized solar cell (DSC) with a storage electrode [8][9][10][11] and a storage battery with a photovoltaic function. 12,13) We have also studied the photorechargeable electrodes that are composites of photoactive and electrochemically storable materials, as shown in Fig. 1(a).…”

A photorechargeable battery (PRB) is a photovoltaic device having an energy storage function in a single cell. The photoactive electrode of PRB is a bilayer film consisting of bare porous TiO 2 and a TiO 2 -polyaniline (PANi) mixture that work as a photovoltaic current generator and an electrochemical energy storage by ion dedoping, respectively. To study the charge transfer between TiO 2 and PANi, the photorechargeable quantum efficiency QE ([electron count on discharge]/[incident photon count on photocharge]) was measured by varying the thickness L S of the TiO 2 -PANi mixture. The quantum efficiency QE uv for UV photons had a maximum of >7% at L S > 7 µm. The time constant τ TP for the charge transfer was about 10 %1 s, which was longer ten times or more than the lifetime of excited electrons within TiO 2 . These facts reveal that the main rate-limiting factor in the photocharging process is the charge transfer between TiO 2 and PANi.

“…A PTFE film is placed over the structure to repel atmospheric water but allow oxygen diffusion. The large surface area of the air-cathode helps it gain a large amount of reaction compared to platinum (Pt) electrodes, which have limited gas-liquid-solid three-phase boundary areas even though meshes are used [15]. Considering its high conductivity at 83.3 S cm −1 and high recyclability [16] the use of air-cathode could have positive impacts on the production of TiO 2 nanotube arrays.…”
