Applications of the Two Dimensional Materials for Energy Storage: Battery Electrodes, Electrolytes and Multi-functional Electrocatalysis
Among various two-dimensional (2D) materials, graphene possesses similar interlayer spacing of multiwalled carbon nanotubes (0.32−0.35 nm) which could be modulated by several strategies such as the intercalation of cations and anions, the nature of the solvent, and surface functionalization. The resultant graphene nanoribbons ( 40 nm diameter) formed by the ionic liquid-assisted transformation of multiwalled carbon nanotubes of an average diameter ( 21 nm) along with graphene quantum dots having an emission wavelength of 445 nm are more useful for some of the specific applications. The tunability of this spacing depends on the nature of the ionic liquid, the size of the incoming ions, the applied potential, and the time. In this lecture several examples of electrochemically prepared 2D materials, their heteroatom doping and surface modification possibility will be discussed using both elemental and compound 2D quantum dots like Graphene, Phosphorene, carbon nitride, Molybdenum Sulphide, Bismuthene and clay based 2D composites will be demonstrated for specific applications like electrocatalysis and battery storage.
