ABSTRACT
With the miniaturization and planarization of energy storage devices, it is urgent to improve the energy density and power density of energy storage devices. Two-dimensional (2D) materials received extensive attention in recent years because of their various advantageous properties, such as good flexibility, chemical stability, and excellent conductivity and thermal conductivity. Effective control of the morphology of 2D materials can improve the specific surface area of materials, increase the number of active sites, and improve the electronic exchange rate, which is a research hotspot in the field of energy. This chapter elaborates the morphology types and construction methods of 2D materials (Graphene, TMDC, TMO, and MXenes) in detail. Subsequently, this chapter introduces the progress of these materials made in both energy conversion and storage devices including supercapacitors, lithium-ion batteries, sodium-ion batteries, and potassium-ion batteries, and discussed in depth. Further, perspectives relating to the challenges and opportunities in this promising field of research are discussed.
