    摘要:

    利用溶剂热法,将前驱体ZIF-8通过高温在氮气保护的气氛下进行碳化,得到高比表面积的多孔碳材料。通过X射线衍射仪分析材料的物相,比表面积分析仪检测材料的比表面积和吸脱附情况,用扫描电镜来观察材料的微观形貌;最后,对多孔碳材料在锂离子电池中的电化学性能进行了测试,0.1C条件下测得的比容量为284.61 mAh/g,且循环性能较好,循环效率在95%以上,表明所制得的多孔碳材料具有良好的储锂性能。

    Abstract:

    As an excellent energy storage device, lithium ion battery has been developed rapidly in recent years, and more and more materials have been applied to lithium ion battery. In this study, porous carbon material has been successfully synthesized by carbonization of ZIF-8 in the atmosphere protected by nitrogen. We analyzed the phase purity of the material by XRD, the pores size distribution and specific surface area were analyzed by nitrogen sorption isotherm techniques. At last, the electrochemical properties of porous carbon material in lithium-ion batteries were investigated. the Results show that the specific capacity measured at 0.1C is 284.61mAh/g with good cycling performance, and the cycling efficiency is more than 95%, which indicates that the obtained carbon material shows remarkable lithium storage performance.
