中文摘要：
采用水热法制备了一种含铝金属有机骨架材料,其在高温下发生炭化得到多孔碳,最后与硫复合制得锂硫电池正极材料. XRD图谱显示在高温炭化时多孔碳样品出现了部分石墨化. N2等温吸附-脱附测试分析显示合成的多孔碳材料含有微孔和介孔结构.对不同载硫量的锂硫电池进行了充放电性能测试,结果显示S质量分数为46.3%的样品在0.01 C倍率下首次放电容量达到1272 mA·h/g；在0.1 C倍率下首次放电容量为934 mA·h/g,循环性能良好.
英文摘要：
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＆#183;h/g at 0.01 C and 934 mA＆#183;h/g at 0.1 C with good cycle performance.
