摘要	The high specific capacity of lithium-sulfur batteries makes them a potential next-generation energy storage device, but the shuttle effect and low electrical conductivity of sulfur hinder their development. In this paper, a one-step hydrothermal method was used to prepare cerium dioxide and metal organic framework composites to improve the electrochemical performance of lithium-sulfur batteries. Polar cerium dioxide has a strong affinity to polysulfides. Experiments further confirmed that CeO2 has a positive effect on the battery performance. UV-Vis tests were performed on the composites. After standing for 1 h, Zn@NPC-CeO2-2 showed the best adsorption of polysulfides. In addition, the specific discharge capacity of the battery was 569.3 mA h/g with 88% capacity retention after 200 cycles at 2 C. The results indicate that the addition of appropriate amounts of rare earth metal oxides can effectively improve the reaction kinetics of the battery and also provide a new idea for improving the performance of lithium-sulfur batteries. © 2022 Elsevier B.V.
