“…In addition to the above characterization, the XPS results are also strong evidence for the formation and reversible decomposition of Li 2 O 2 . The Li 1s signal at 55.0 eV in Figure f and the O 1s signal at 531.2 eV in Figure g demonstrate the formation of Li 2 O 2 after discharge, while both the Li 1s and O 1s signals representing Li 2 O 2 disappear after charging. , The above research results reveal that the electrochemical reactions in the integrated solid-state Li–O 2 battery based on PLCSSE10 are reversible, accompanied by the formation and efficient decomposition of Li 2 O 2 , which are similar to the traditional liquid Li–O 2 batteries. , This design strategy provides new ideas for regulating the interface and realizing improved performances of Li–O 2 batteries.…”

A composite solid-state electrolyte (SSE) with acceptable safety and durability is considered as a potential candidate for high-performance lithium–oxygen (Li–O2) batteries. Herein, to address the safety issues and improve the electrochemical performance of Li–O2 batteries, a solvent-free composite SSE is prepared based on the thermal initiation of poly(ethylene glycol) diacrylate radical polymerization, and an integrated battery is achieved by injecting an electrolyte precursor between electrodes during the assembly process through a simple heat treatment. The Li-metal symmetric cells based on this composite SSE achieve a critical current density of 0.8 mA cm–2 and a stable cycle life of over 900 h at a current density of 0.2 mA cm–2. This composite SSE effectively inhibits the erosion of O2 on the Li metal anode, optimizes the interface between the electrolyte and cathode, and provides abundant reaction sites for the electrochemical reactions during cycling. The integrated solid-state Li–O2 battery prepared in this work achieves stable long cycling (118 cycles) at a current density of 500 mA g–1 at room temperature, showing the promising future application prospects.

“…Due to their ultrahigh theoretical energy densities (about 3500 Wh kg −1 ), they have been considered as the most promising nextgeneration high-specific energy storage systems. [86,87] To even-tually produce Li-O 2 batteries with high specific capacity, high power, and long-term stability (or cycling Li-O x batteries), the biggest challenge that has to be overcome is to avoid the side reactions since they enhance the overcharge potential and impair the cycling performance of Li-O 2 batteries. Interestingly, lightassisted charging effectively reduced the overpotential of the Li-O 2 cells.…”

Various energy storage devices are highly demanded by o ur modern society. The use of solar energy, an important green energy source, is extremely attractive for future energy storage. Recently, photo‐assisted energy storage devices have rapidly developed as they efficiently convert and store solar energy, while their configurations are simple and their external energy decline is much reduced. Light‐assisted energy storage devices thus provide a potential way to utilize sunlight at a large scale that is both affordable and limitless. Considering rapid development and emerging problems for photo‐assisted energy storage devices, this review starts with the fundamentals of batteries and supercapacitors and follows with the state‐of‐the‐art photo‐assisted energy storage devices where device components, working principles, types, and practical applications are explained. After the detailed demonstration of some photo‐assisted energy storage devices examples, the bottleneck of such light‐assisted energy storage devices is discussed and the prospects of the light‐assisted rechargeable devices are further outlined.

Lithium-ion batteries (LIBs) have dominated the portable electronic and electrochemical energy markets since their commercialisation, whose high cost and lithium scarcity have prompted the development of other alkali-ion batteries (AIBs) including sodium-ion batteries (SIBs) and potassium-ion batteries (PIBs). Owing to larger ion sizes of Na+ and K+ compared with Li+, nanocomposites with excellent crystallinity orientation and well-developed porosity show unprecedented potential for advanced lithium/sodium/potassium storage. With enticing open rigid framework structures, Prussian blue analogues (PBAs) remain promising self-sacrificial templates for the preparation of various nanocomposites, whose appeal originates from the well-retained porous structures and exceptional electrochemical activities after thermal decomposition. This review focuses on the recent progress of PBA-derived nanocomposites from their fabrication, lithium/sodium/potassium storage mechanism, and applications in AIBs (LIBs, SIBs, and PIBs). To distinguish various PBA derivatives, the working mechanism and applications of PBA-templated metal oxides, metal chalcogenides, metal phosphides, and other nanocomposites are systematically evaluated, facilitating the establishment of a structure–activity correlation for these materials. Based on the fruitful achievements of PBA-derived nanocomposites, perspectives for their future development are envisioned, aiming to narrow down the gap between laboratory study and industrial reality.
