The slow bidirectional conversion and fast shuttling of lithium polysulfides (LiPSs) remain the main obstacles that inhibit the practical application of lithium sulfur batteries (LSBs). Here, by engineering the in-spin state of spinel oxides, V doping-induced hexagonal nanosheets (V-CoO NS) with intermediate spin state (IS, t e) can form stable bond order toward LiS based on the ligand field theory and molecular orbital theory, thus effectively accelerating the sulfur conversion kinetics. Owing to these merits, the V-CoO NS modified separator base battery achieves a high areal capacity of 15.37 mAh cm with sulfur loading of 15.4 mg cm, and it displays a low-capacity attenuation of 0.015% each cycle at 3.0 C for 1900 cycles.
