“…Apart from their application in all-solid-state LIBs, halide SSEs have also been used in other electrochemical energy storage systems ( Fig. 6A ), such as all-solid-state Li-S batteries ( 43 ), all-solid-state Li-Se batteries ( 102 ), solid-state Li-O 2 batteries ( 73 ), and all-solid-state Na-ion batteries ( 56 ). Compared with all-solid-state LIBs, Li-S chemistry offers higher energy density (2600 Wh kg −1 ), better cost-effectiveness, and compatibility with halide SSEs.…”

The safety of lithium-ion batteries has caused notable concerns about their widespread adoption in electric vehicles. A nascent but promising approach to enhancing battery safety is using solid-state electrolytes (SSEs) to develop all-solid-state batteries, which exhibit unrivaled safety and superior energy density. A new family of SSEs based on halogen chemistry has recently gained renewed interest because of their high ionic conductivity, high-voltage stability, good deformability, and cost-effective and scalable synthesis routes. Here, we provide a comprehensive review of halide SSEs concerning their crystal structures, ion transport kinetics, and viability for mass production. Furthermore, their moisture sensitivity and interfacial challenges are summarized with corresponding effective strategies. Last, halide-based all-solid-state Li-ion and Li-S pouch cells with energy density targets of 400 and 500 Wh kg −1 are projected to guide future endeavors. This work serves as a comprehensive guideline for developing halide SSEs from material design to practical application.

Cryo-EM Revealing the Origin of Excessive Capacity of the Se Cathode in Sulfide-Based All-Solid-State Li–Se Batteries

Selenium (Se), whose electronic conductivity is nearly 25 orders higher than that of sulfur (S) and whose theoretical volumetric capacity is 3254 mAh cm–3, is considered as a potential alternative to S to overcome the poor electronic conductivity issue of the S cathode in the lithium (Li)-S battery. However, the study of the Li–Se battery, particularly a Li–Se all-solid-state battery (ASSB), is still in its infancy. Herein, we report the performance of Li–Se ASSBs at both room temperature (RT) and high temperature (HT, 50 °C), using a Li10Si0.3PS6.9Cl1.8 (LSPSCl) solid-state electrolyte and Li-In anode. With a Se loading of 7.6 mg cm–2, the Li–Se battery displayed a record high reversible capacity of 6.8 mAh cm–2 after 50 cycles at HT, which exceeds the theoretical areal capacity of 5.2 mAh cm–2 for Se. Moreover, the RT Li–Se ASSB delivered an initial areal capacity of about 2 mAh cm–2 at a current density of 1 A g–1 for 1200 cycles with a capacity retention of 67%. Cryo-electron microscopy revealed that the excessive capacity of Se at HT can be attributed to the formation of a previously unknown S5Se4 phase during charging, which participated reversibly in a subsequent redox reaction. The formation of the S5Se4 phase originated from the reaction of Se with S, which was generated by the decomposition of LSPSCl at HT. These results unlock the electrochemistry of a Li–Se ASSB, suggesting that a Li–Se ASSB is a viable alternative to a Li–S battery for energy storage applications.

“…Li 3 MX 6 (M = Sc, In, Er, Y, Ho, X= Cl, Br) electrolytes are some of the typical materials . These promising properties are commercially important for solid energy sources. , Lithium phosphorus oxynitride (LiPON) has received attention since its discovery by Bates et al , in the 1990s and has been used in commercial thin-film solid-state LIBs for years, which shows a simple manufacturing process and outstanding cycling property . However, due to the low ionic conductivity (approximately 10 –6 S cm –1 ) at room temperature and relatively high preparation cost ( via vacuum deposition), the application of LiPON-based LIBs is limited to low-energy devices such as smart cards and microelectronics …”

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.
