摘要:

鋰硫電池因其具有高的理論能量密度，近年來成為高性能二次電池領域的研究熱點。為了有效提升鋰硫電池的電化學性能，具有孔徑分布可控、孔隙率高以及易于功能化等諸多優點的金屬有機骨架（MOFs）材料被廣泛探索研究。通過對MOFs材料進行修飾改性，制備的多種MOF復合材料、MOF衍生材料表現出了更優的電化學性能，有效提升了電極反應動力學、改善了電池循環性能。針對當前鋰硫電池研究中的關鍵問題，對各類MOFs材料、MOF復合材料和MOF衍生材料在鋰硫電池正極中應用的研究進展進行了綜述，并對未來MOF基材料在鋰硫電池正極中應用的發展趨勢作出了展望。

Abstract:

Due to their high theoretical energy density, lithium-sulfur batteries have become the research hotspot in the field of high-performance rechargeable batteries in recent years. In order to effectively improve the electrochemical performance of lithium-sulfur batteries, metal-organic frameworks (MOFs) with controllable pore size distribution, ultrahigh porosity and easy functionalization ability have been extensively explored and studied. By modifying MOFs, various MOF composites and MOF derivatives have showed better electrochemical performance, which effectively improve reaction kinetics of electrodes and cycling performance of batteries. In this paper, research progresses of various MOFs, MOF composites and MOF derivatives in cathode of lithium-sulfur batteries were reviewed based on the key issues in the current research of lithium-sulfur batteries, and the future development trends of MOF-based materials-application in cathode of lithium-sulfur batteries were put forward.
