Abstract The weak bonding of A atoms with MX layers in MAX phases not only enables the selective etching for MXene preparation but brings about chance to construct derivatives/MXene composites via situ conversion. Here, a facile and general gas‐solid reaction systems are elegantly devised multi‐dimensional based including AlF 3 nanorods/MXene, nanocrystals/MXene, amorphous /MXene, filled carbon nanotubes/MXene, layered metal chalcogenides/MXene, MOF/MXene, so on. intrinsic effect mechanism interlayer confinement towards crystal growth, catalytic behavior, van der Waals‐heterostructure construction coordination rationally put forward. tight interface combination synergistic from distinct components make them promising active materials electrochemical applications. More particularly, nanorods/Nb 2 C demonstrate bi‐directional activity toward conversion between Li S lithium polysulfides, which alleviates shuttle lithium‐sulfur batteries.

Abstract Alkali metal‐sulfur batteries (MSBs) are one of the most promising next‐generation energy storage technologies due to their high density and potential for low cost. They nonetheless constrained by sluggish conversion metal polysulfides (MPS) during charge/discharge process. Herein, a multifunctional separator able trap MPS catalyze in three main MSB chemistries, Li‐, Na‐, K‐MSBs, is demonstrated. More detail, SnSe nanosheets introduced as additive into cathode side glass microfiber (GF) MSB. Taking lithium‐sulfur (LSBs) an example, it demonstrated that GF‐SnSe (GF@SnSe) shows strong chemical affinity lithium (LiPS) superior catalytic activity, inhibiting transport LiPSs anode accelerating conversion. Combining experimental calculation results, shown decrease Li 2 S decomposition barrier. Overall, GF@SnSe separators provide significantly improved LSB rate performance cycling stability with 0.049% capacity decay per cycle. Besides, promotes electrochemical sodium‐sulfur potassium‐sulfur batteries. this work presents significant advancement development LSBs well emerging Na‐S K‐S systems.
