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 Flexible Zn 2+ ion hybrid capacitors (ZHCs) will play a crucial role in developing next‐generation wearable products, which demand portability, durability, and environmental adaptability. To further meet these requirements, Ti 3 C 2 T x MXene with exceptional conductivity robust mechanical properties can be utilized as cathodes, except for challenges such the dense stacking of nanosheets. In this study, novel cathode architecture has been developed facilitation an ice template, creates longitudinally aligned arrays microchannels. The introduction hydrochloric acid to slurry induces crumpled morphology, increasing active sites enhancing transport expanded interlayer spacing. Interestingly, experimental results COMSOL simulations verify that structure also effective impacts on anode weakened concentration gradient suppressed dendrite formation. Consequently, ZHCs exhibit enhanced electrochemical performance excellent rate long‐term cycling stability (enduring over 50 000 cycles at 5 A g −1 ) deliver reliable low‐temperature operation by applying anti‐freezing electrolyte. Moreover, flexible assembled gel electrolytes demonstrate flexibility, improved performance, stability, making them well‐suited electronics power LED panels.

Lithium-sulfur (Li-S) batteries have the characteristics of low cost, environmental protection, and high theoretical energy density, broad application prospects in new generation electronic products. However, there are some problems that seriously hinder Li-S from going laboratory to factory, such as poor stability caused by large volume expansion sulfur during charging discharging, sluggish kinetics electrochemical reaction resulting conductivity active materials, loss materials arising dissolution diffusion intermediate product lithium polysulfides (LiPSs). In this paper, two-dimensional layered material MXene TiN firstly combined spray drying method prepare pomegranate-like TiN@MXene microspheres with both adsorption capacity catalytic effect on LiPSs conversion. The interconnected skeleton composed not only solves problem easy stacking sheets but also ensures uniform distribution sulfur. Without affecting excellent itself, overall composite electrode is improved. hollow nanospheres coated layers form a shell, catalyzing accelerating transformation high-order Li2S2/Li2S. As result, cathode delivers initial discharge 1436 mA h g-1 at 0.1C, rate performance 636 up 3C, an ultralong lifespan over 1000 cycles small decay 0.048% per cycle current density 1.0C.
