“…Moreover, the combination of MXene with metal− organic frameworks (MOFs) is also a common method. 65,66 MOFs have an excellent pore structure and coordinated metal nodes, which provide sufficient reaction and catalytic sites for the reaction of sulfur. However, most MOFs have poor conductivity; therefore, high-temperature carbonization treatment has become a favorable means.…”

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

“…Besides, the conventional separator is easily pierced by the lithium dendrites formed during the charge/discharge process, leading to latent safety hazard [13] . The surface coating on the separator has been proved to be an effective approach to confine the polysulfides migration as well as enhance the mechanical strength of the separator [14] . Here, the coating materials greatly affect the functionality of the coated separator.…”

Nano‐LaMnO₃ Modified Separator for Enhanced Redox Reaction Kinetics and Electrochemical Performance of Lithium‐Sulfur Batteries

The “shuttle effect” and sluggish conversion reaction kinetics of polysulfides seriously hinder the practical application of Li‐S batteries. In this study, nano‐sized LaMnO3 (N‐LMO) with typical perovskite structure combined with highly‐conductive carbon black (SP) was introduced on the commercial separator to fabricate a functional surface modification. It is found that the polar N‐LMO with abundant active sites offers strong chemisorption towards the soluble polysulfides meanwhile accelerates their redox conversion, and the conductive SP contributes to extra spots to reactivate the trapped sulfur species. Consequently, the synergistic effect of adsorption‐catalysis‐conduction built by the cooperative N‐LMO/SP modification greatly enhances the sulfur redox kinetics as well as suppresses the polysulfide shuttling not at the expense of weakening Li‐ion transport, which endows the Li‐S cell with a high initial discharge capacity of 1143.6 mAh g−1 at 0.2 C and a capacity decay rate of only 0.072% per cycle at 1 C over 500 cycles.
