Abstract Practical application of lithium–sulfur (Li–S) batteries is severely impeded by the random shuttling soluble lithium polysulfides (LiPSs), sluggish sulfur redox kinetics, and uncontrollable growth dendrites, particularly under high loading lean electrolyte conditions. Here, nitrogen‐doped bronze‐phase TiO 2 (B) nanosheets with oxygen vacancies (OVs) grown in situ on MXenes layers (N‐TiO 2− x (B)‐MXenes) as multifunctional interlayers are designed. The N‐TiO (B)‐MXenes show reduced bandgap 1.10 eV LiPSs adsorption‐conversion‐nucleation‐decomposition efficiency, leading to remarkably enhanced kinetics. Moreover, they also have lithiophilic nature that can effectively suppress dendrites growth. cell based interlayer 2.5 mg cm −2 delivers superior cycling performance a specific capacity 690.7 mAh g −1 over 600 cycles at 1.0 C. It still has notable areal 6.15 after 50 even 7.2 low electrolyte‐to‐sulfur (E/S) ratio 6.4 µL .
