Graphene-CNT Hybrid Structures for Energy Storage Applications

The utilization of graphene and carbon nanotubes (CNTs) has become prevalent in diverse applications, including energy storage devices such as batteries and supercapacitors. The combination of graphene and CNT is of particular interest, resulting in hybrid structures that exhibit the excellent properties of both constituents. This chapter presents various synthesis methods for fabricating graphene-CNT hybrid structures, specifically focusing on the chemical vapor deposition (CVD) method. Furthermore, the energy storage device applications of the graphene-CNT hybrid structure are discussed based on the literature and our experimental data.
