Abstract Lithium‐sulfur (Li–S) battery with high capacity and energy density is a promising next‐generation storage device. However, the shuttle effect of polysulfides causes low utilization sulfur side reactions at electrode interface. The electrode/electrolyte interface determines chemical activity electrochemical reversibility as well cycling stability battery. Therefore, ideal in Li–S depends on loading, fast ion diffusion, effective active intermediates, uniform deposition lithium anode. MXene two dimension layer structure, good conductivity, abundant terminal groups can serve carrier to load sulfur, anchor polysulfides, accelerate transfer. This review summarizes three strategies MXene‐based interfaces including host interface, functional separator anode based principles challenges In addition, interfacial regulation application materials focus process are also presented. Finally, further prospective discussed.

Hydrogel materials containing gelatin can improve the biocompatibility and biodegradability of sensing materials, so they be widely used in flexible sensors, health monitoring, smart electronic devices. In this paper, using as a biomass-based material, interpenetrating network structure formed between polyacrylamide could not only strong stretchability flexibility hydrogel but also provide more binding sites for conductive materials. Then, polyacrylamide–gelatin MXene (PGMH) sensor with excellent performance tensile strength was prepared by introducing into structure. addition to enhancing mechanical properties hydrogel, electrical conductivity are effectively improved wearable device; breathability material ensure its adequate wear safety comfort. Importantly, feedstock gives it stability comfort use. The designed has good wide applicability great application potential next generation degradable
