“…Specifically, carbonates tend to react with the discharge components to form lithium carbonates and alkyl carbonates, which can decompose to produce CO 2 instead of O 2 during charging, leading to irreversible loss of the solvent and also the rapid capacity loss and early failure of LOBs . Explorations have been carried out and revealed that the decomposition of organic carbonates, sulfonate esters, aliphatic carboxylic esters, lactones, sulfones, and alkyl esters of phosphinic, phosphonic, and phosphoric acids could be caused by the nucleophilic attack of superoxide on the O -alkyl carbon. , This has triggered research on the development of solvents including ether-based (e.g., DME, TEGDME), DMSO, acetonitrile, and silane-based solvents, etc. , Especially, TEGDME has been considered to be a promising solvent with good stability to combat superoxide radicals in the process of charge and discharge of LOBs (Figure a). , In this regard, GPEs based on PVDF-HFP and TEGDME plasticizers have been developed for LOBs . As reported, PVDF-HFP with large polarized C–F bonds was prone to cross-link with TEGDME through O and F atoms by Li + ions (Figure b).…”

The ever-increasing demand for flexible and portable electronics has stimulated research and development in building advanced electrochemical energy devices which are lightweight, ultrathin, small in size, bendable, foldable, knittable, wearable, and/or stretchable. In such flexible and portable devices, semi-solid/solid electrolytes besides anodes and cathodes are the necessary components determining the energy/power performances. By serving as the ion transport channels, such semi-solid/solid electrolytes may be beneficial to resolving the issues of leakage, electrode corrosion, and metal electrode dendrite growth. In this paper, the fundamentals of semi-solid/solid electrolytes (e.g., chemical composition, ionic conductivity, electrochemical window, mechanical strength, thermal stability, and other attractive features), the electrode–electrolyte interfacial properties, and their relationships with the performance of various energy devices (e.g., supercapacitors, secondary ion batteries, metal–sulfur batteries, and metal–air batteries) are comprehensively reviewed in terms of materials synthesis and/or characterization, functional mechanisms, and device assembling for performance validation. The most recent advancements in improving the performance of electrochemical energy devices are summarized with focuses on analyzing the existing technical challenges (e.g., solid electrolyte interphase formation, metal electrode dendrite growth, polysulfide shuttle issue, electrolyte instability in half-open battery structure) and the strategies for overcoming these challenges through modification of semi-solid/solid electrolyte materials. Several possible directions for future research and development are proposed for going beyond existing technological bottlenecks and achieving desirable flexible and portable electrochemical energy devices to fulfill their practical applications. It is expected that this review may provide the readers with a comprehensive cross-technology understanding of the semi-solid/solid electrolytes for facilitating their current and future researches on the flexible and portable electrochemical energy devices.

Gradient Mn-La-Pt catalysts with three-layered structure of manganese dioxide (MnO2), lanthanum oxide (La2O3), and Platinum (Pt) for Li-O2 battery are prepared in this study. The mass ratio of the catalysts is respectively 5:2:3, 4:2:4, and 3:2:5 (MnO2: La2O3: Pt) which is start from the side of the electrolyte. The relationship between morphology structure and electrochemical performance of gradient catalyst is investigated by energy dispersive spectrometry and constant current charge/discharge test. The Li-O2 battery based on gradient Mn-La-Pt catalysts shows high discharge specific capacity (2707 mAh g−1), specific energy density (8400 Wh kg−1) and long cycle life (56 cycles). The improvement of the Li-O2 battery discharge capacity is attributed to the gradient distribution of MnO2 and Pt and the involvement of La2O3 that can improve the energy density of the battery. More important, this work will also provide new ideas and methods for the research of other metal-air battery.
