Transition Metal Dichalcogenides for Energy Storage Applications

Energy storage techniques based on supercapacitors and secondary batteries play important roles in the current energy fields. They all face some technical challenges which need to be addressed urgently to satisfy the increasing demand for modern clean energy technologies. In these electrochemical energy storage devices, two-dimensional monolayered transition metal dichalcogenides (2D TMDs) may play particular roles in improving many aspects of performances owing to their thin structure, large surface area, high surface tenability, and both “Faradaic” and “non-Faradaic” electrochemical behaviors. This chapter gives an overview of energy storage techniques based on conventional and newly developed supercapacitors and secondary batteries and discusses on how to engineer 2D TMDs to enable them to find promising applications in the area.
