Lithium–sulfur batteries (LSBs) are a new type of energy storage system with great potential, which has an ultrahigh density 2600 Wh kg–1. However, the polysulfide shuttle and dendrite growth have seriously impeded practical applications. As two-dimensional (2D) transition metal carbide/nitride, MXene possesses advantages conductivity, structural diversity, abundant terminal groups. Thus, it is beneficial to regulate dynamic process ions, make widely applied in LSBs. Guided by multifunction LSBs, this work summarizes application for cathode construction, separator modification, anode protection, electrolyte regulation. Recent related works reviewed from aspects MXene-based morphology adjustment, element doping, surface composite material construction. Finally, challenges prospects prospected.

Abstract The lithium deposited via the complex electrochemical heterogeneous deposition reaction (LDR) process on a foil‐based anode (LFA) forms high‐aspect‐ratio shape whenever kinetics reach its limit, threatening battery safety. Thereby, research strategy that boosts LDR is needed to construct high‐power and safe metal anode. In this study, kinetic limitations of LFA are elucidated through operando ex situ observations using in‐depth analyses. addition, ultra‐thin (≈0.5 µm) high modulus (≥19 GPa) double‐walled carbon nanotube (DWNT) membranes with different surface properties designed catalyze high‐safety LDRs. oxygen‐functionalized DWNT introduced top simultaneously induce multitudinous nuclei, leading film‐like even at current density 20 mA cm −2 . More importantly, layer‐by‐layer assembly pristine results in energies between bottom surfaces, enabling selective LDRs underneath high‐modulus bilayer membranes. protective bilayer‐covered guarantees an invulnerable cycling large‐area pouch cells densities for more than 1000 cycles, demonstrating practicability conventional liquid electrolyte system.
