The lithium-sulfur battery is the subject of much recent attention due to the high theoretical energy density, but practical applications are challenged by fast decay owing to polysulfide shuttle and electrode architecture degradation. A comprehensive study of the sulfur host microstructure design and the cell architecture construction based on the MXene phase (Ti₃C₂T_x nanosheets) is performed, aiming at realize stable cycling performance of Li–S battery with high sulfur areal loading. The interwoven KB@Ti₃C₂T_x composite formed by self-assembly of MXene and Ktejen black, not only provides superior conductivity and maintains the electrode integrality bearing the volume expansion/shrinkage when used as the sulfur host, but also functions as an interlayer on separator to further retard the polysulfide cross-diffusion that possibly escaped from the cathode. The KB@Ti₃C₂T_x interlayer is only 0.28 mg cm⁻² in areal loading and 3 μm in thickness, which accounts a little contribution to the thick sulfur electrode; thus, the impacts on the energy density is minimal. By coupling the robust KB@Ti₃C₂T_x cathode and the effective KB@Ti₃C₂T_x modified separator, a stable Li–S battery with high sulfur areal loading (5.6 mg cm⁻²) and high areal capacity (6.4 mAh cm⁻²) at relatively lean electrolyte is achieved.

锂硫电池由于理论能量密度高而成为近年来备受关注的主题，但由于多硫化物穿梭和电极结构退化，实际应用受到快速衰减的挑战。_{对硫主体微观结构设计和基于MXene相（Ti 3} C ₂ T _x纳米片）的电池架构构建进行了全面研究，旨在实现高硫面积负载的Li-S电池的稳定循环性能。由 MXene 和 Ktejen 黑自组装形成的交织的 KB@Ti ₃ C ₂ T _x复合材料，不仅提供了优异的导电性，并在用作硫主体时保持了承受体积膨胀​​/收缩的电极完整性，而且还起到了隔膜上的中间层进一步阻止可能从阴极逸出的多硫化物交叉扩散。KB@Ti ₃ C ₂ T _x中间层的面积负载仅为0.28 mg cm ^-2，厚度为3 μm，对厚硫电极贡献不大；因此，对能量密度的影响很小。通过耦合坚固的 KB@Ti ₃ C ₂ T _x阴极和有效的 KB@Ti ₃ C ₂ T _x改性隔膜，可以得到具有高硫面积负载（5.6 mg cm ^-2）和高面积容量（在相对贫电解质下实现了6.4 mAh cm ^{-2 )。}
