Abstract:

An aluminum metal-organic framework(MOF) was prepared by hydrothermal method. Porous carbon was produced by direct carbonization of MOFs and then was loaded with sulfur. XRD patterns show that the porous carbon is partially graphitized during the high temperature carbonization. N2 sorption isotherms illustrate that the porous carbon contain both microporous and mesoporous structures. Charge-discharge tests were carried out among hierarchically sulfur loading lithium sulfur batteries. The initial discharge capacity of S/C-46.3 sample is 1272 mA·h/g at 0.01 C and 934 mA·h/g at 0.1 C with good cycle performance.

Key words: Metal-organic framework, Porous carbon, Cathode material, Lithium sulphur battery(Ed.: F, K, M)
