Abstract:A high specific surface area Al-based metal organic frameworks (MOFs) material Al-ABTC was prepared by hydrothermal synthesis. Then the Al-ABTC and graphene oxide (GO) were compounded by electrostatic adsorption method, and sulfur was loaded to obtain Al-ABTC/RGO@S composite material for lithium-sulfur battery. The crystal structure of Al-ABTC was analyzed by X-ray diffraction (XRD), the octahedral morphology of Al-ABTC, Al-ABTC/GO and Al-ABTC/RGO@S was characterized by scanning electron microscope (SEM), and the electrochemical performance of the material was tested by constant current charge and discharge. The results show that the initial discharge capacity of the Al-ABTC/RGO@S composite electrode reaches 1345.3 mAh g-1 at 0.2 C rate, decayes to 406.4 mAh g-1 after 200 cycles, and the average coulombic efficiency is 99.1%. In addition, even at 2 C, an initial reversible capacity of 714.7 mAh g-1 was received and a capacity of 331 mAh g-1 after 300 cycles, showing an excellent long-term cycling performance.
