Although Li–S batteries have a high theoretical capacity, their application are significantly hindered by the complex shuttle effect of polysulfides. To address issues, in this paper, Ni 2 V O 7 prepared simple method is proposed as an efficient catalyst for S cathodes. composed Ni–O octahedra and V–O tetrahedra has specific electronic structure. The atoms interacted, enabling fast kinetics polysulfide redox. Moreover, contains metal sites (Ni V) oxygen vacancies, providing adsorption capacity abundant active Therefore, consisting -based cathodes exhibit excellent cycling stability with 1061 mAh g −1 retention 87.6 % after 150 cycles at 0.2 C. 1 C rate, 706 300 minimal decay only 0.08 per cycle.
