摘要
开发了共球磨两种异质层状材料一步制备MoS2/石墨烯(r GO)纳米复合材料的新方法.两种层状物质在被剥离的同时均匀复合,因此该材料具有良好的导电性、高的电化学反应活性位点以及优异的结构稳定性.在电流密度为0.5 A·g^-1时,比电容约为306 F·g^-1,大约为纯MoS2的两倍.作为锂离子电池正极材料,在0.2 A·g^-1电流密度下循环100次几乎没有比容量的衰减.
This work developed a novel method of ball-milling two heterogeneous layered materials together to prepare MoS2/rGO nanocomposites. The two layered substances are simultaneously stripped and re-combined uniformly, so that the composites have good electrical conductivity, high electrochemical reactive sites and excellent structural stability. The MoS2/rGO nanocomposite as electrode material used in supercapacitor delivers a high specific capacitance of 306 F·g^-1 at a current density of 0.5 A·g^-1 and approximately two times higher than that of the pure MoS2. Besides, it exhibits nearly no discharge capacity decay used in lithium ion batteries(0.2 A·g^-1 after 100 cycles).
