摘　　要：石墨烯是一种由碳原子以sp^2杂化轨道结合,呈六角型蜂巢晶格的二维平面材料,是构成碳质材料的基本单元。石墨烯是目前强度最大、导电导热性能最强的材料,在传感器、电池和超级电容器等领域有广泛的应用。但是在电池和超级电容器应用中,石墨烯与电解液的接触面积仍比较小,一维碳纳米管阵列垂直生长在石墨烯平台上,形成三维碳纳米管阵列/石墨烯,可进一步扩大石墨烯与电解液的接触面积同时产生协同效应,显著提高电池和超级电容器的性能。综述了三维碳纳米管阵列/石墨烯的制备方法及在电池和超级电容器中的应用。Graphene with 2D monolayer of sp2-carbon atoms arranged in a honeycomb network is a basic unit of carbonaceous material.Graphene has the largest strength,highest electrical and thermal conductivity.It have been applied in the field of sensor,battery and supercapacitor.However,the contact area of graphene and electrolyte is still relatively small in battery and supercapacitor.One-dimensional carbon nanotube arrays can be vertically grown on graphene platform to form 3D carbon nanotube arrays/graphene composite,which can increase the contact area with the electrolyte and improve their performance.The preparation methods of 3D carbon nanotube arrays/graphene and its application in battery and supercapacitor were mainly reviewed.
