Environment friendly, lightweight, and safe electrochemical energy storage devices have vast applications in almost every part of our life, including the field of electric vehicles and portable electronics, to name just a few [1]. The performance of energy storage devices such as batteries and capacitors are largely determined by the intrinsic properties of the electrode materials used within them. Therefore, the development of lightweight energy storage devices with high energy density is a very active and challenging field of research.
MXenes, being a rather young member of the family of 2D materials introduced in 2011, have gained significant attention due to their unique physiochemical properties. Synthesis of MXenes from its parent, MAX phases. It is expected that different synthesis methods including the synthesis parameters modify the local atomic structure of the MXenes which in turn affect the electronic properties. Though many research groups around the world are working on various synthesis methods of MXene, its characterization and properties; until now there is no report to establish a direct link between the synthesis methods of MXenes with their local atomic structures and electronic properties. My thesis aims to bridge the gap. The objective of the work is to link the various synthesis methods of MXenes (Ti and V based carbides and carbonitrides) with their atomically resolved 3D local structure and electronic properties. It is expected that the resulting data of this work will open up a new window for the researchers to tune the synthesis procedures of MXenes as per the requirement of specific energy storage applications.
