摘要	Development of lithium-sulfur batteries faces various challenges, thus it is crucial to design efficient cathode material. We designed a dual carbon source precursor material, which benefits form merging the characteristics of the huge specific surface area of the MOF material and the excellent conductivity of carbon nanotubes to improve the performance of the lithium-sulfur battery. Furthermore, the added nickel-rich metal phosphide can effectively improve the material's ability to adsorb polysulfides. When the addition amount of carbon nanotubes is optimized, the polarization voltage of the battery is reduced, which is conducive to the reaction kinetics of the battery. Due to the above-mentioned advantageous features, the specific capacity of the battery reaches 1453.5 mAh/g at a cycle rate of 0.1 C. In addition, after 500 cycles at 1 C, the coulombic efficiency of the battery always remains above 96%, and the retention rate of specific capacity is also above 90%. © 2021 Elsevier B.V.
