Two-Dimensional Materials Based Flexible Electrodes for Energy Storage

The rapid growth of portable electronics, especially wearable/bendable devices, has driven the development of compliant and reliable energy storage units with high energy and power density. Being the key components in such flexible energy storage devices, the development of flexible electrodes has drawn tremendous research interest. The discovery of two-dimensional (2D) materials (e.g. graphene) and their rapid development have led to the availability of a range of 2D materials including transition metal dichalcogenides (TMDs), boron nitrides and MXenes. This has also triggered the development of 2D materials-based flexible electrodes owing to their outstanding mechanical properties, large surface area and excellent electrochemical properties. The main issue existing concerning these electrodes is the limited electrochemical performance as a result of the restacked/aggregated 2D nanosheets. This thesis focuses on the development of flexible 2D materials-based electrodes with three-dimensional (3D) porous structures that prevents the restacking of those 2D nanosheets for achieving high performance.
