“…[146,147] After 100 cycles, at 100 and 500 mA g −1 , the stable discharge capacity of the all-solidstate lithium battery is maintained at 436.8 and 270.4 mA h g −1 respectively. [148] Furthermore, compared with bulk TMCs, 2D TMCs have high mechanical strength, which not only can used as host material for active material-sulfur, but also can deliver high reversible specific capacity for ASSLBs. Xu et al designed a new type of intercalation-conversion hybrid cathode with VS 2 nanosheets which was used in ASSLBs (Figure 6c).…”

Althoughone of the most mature battery technologies, lithium-ion batteries still have many aspects that have not reached the desired requirements, such as energy density, current density, safety, environmental compatibility, and price. To solve these problems, all-solid-state lithium batteries (ASSLB) based on lithium metal anodes with high energy density and safety have been proposed and become a research hotpot in recent years. Due to the advanced electrochemical properties of 2D materials (2DM), they have been applied to mitigate some of the current problems of ASSLBs, such as high interface impedance and low electrolyte ionic conductivity. In this work, the background and fabrication method of 2DMs are reviewed initially. The improvement strategies of 2DMs are categorized based on their application in the three main components of ASSLBs: The anode, cathode, and electrolyte. Finally, to elucidate the mechanisms of 2DMs in ASSLBs, the role of in situ characterization, synchrotron X-ray techniques, and other advanced characterization are discussed.

“…Since then, those high-tap density hosts which can provide extra capacity by Li intercalation reaction and afford strong LiPSs affinity were constantly reported. 152,153 Another example is the use of a lithium-transfer bridging agent to facilitate the effective conversion of both sulfur and LiPSs to the final Li 2 S product (Figure 5G). 139 In that work, two pseudocapacitive oxides, namely orthorhombic Nb 2 O 5 and birnessite MnO 2 , were devised as desirable electron-ion source and drain, respectively.…”

As one of the most promising candidates for next-generation energy storage systems, lithium-sulfur (Li-S) batteries have gained wide attention owing to their ultrahigh theoretical energy density and low cost. Nevertheless, their road to commercial application is still full of thorns due to the inherent sluggish redox kinetics and severe polysulfides shuttle. Incorporating sulfur cathodes with adsorbents/catalysts has been proposed to be an effective strategy to address the foregoing challenges, whereas the complexity of sulfur cathodes resulting from the intricate design parameters greatly influences the corresponding energy density, which has been frequently ignored. In this review, the recent progress in design strategies of advanced sulfur cathodes is summarized and the significance of compatible regulation among sulfur active materials, tailored hosts, and elaborate cathode configuration is clarified, aiming to bridge the gap between fundamental research and practical application of Li-S batteries. The representative strategies classified by sulfur encapsulation, host architecture, and cathode configuration are first highlighted to illustrate their synergetic contribution to the electrochemical performance improvement. Feasible integration principles are also proposed to guide the practical design of advanced sulfur cathodes. Finally, prospects and future directions are provided to realize high energy density and long-life Li-S batteries.

“…[4][5][6][7][8][9][10] However, during the charge and discharge process, the S cathode quickly generates polysulfides that are soluble in the liquid electrolyte, forming a shuttle effect between the cathode and anode, resulting in low coulombic efficiency and short span life of lithium-sulfur batteries. [11][12][13][14] Replacing the liquid electrolyte with solid electrolyte to fabricate solid-state batteries can physically block polysulfides, avoid the shuttle effect, and improve safety and energy density. [15][16][17] However, sulfur suffers the large volume changes and low electronic conductivity.…”
