Description

This chapter comprises of the basics and fundamentals of electrochemistry, electrochemical (EC) sensors, various EC methods such as voltammetric, amperometric, potentiometric etc. and electrode processes. It provides a state-of-the-art literature survey on graphene (Gr) and molybdenum disulphide (MoS2) based materials in EC sensing and a brief knowledge on the EC properties of Gr and MoS2. Further this chapter explores the basics and challenges of EC energy storage, particularly silicon (Si) based anodes in lithium ion batteries (LIBs), and a brief literature survey on the strategies adopted to improve the battery performance of Si anodes in LIBs, and the role of Gr for the same. Finally, the chapter briefs about the motivation of our research work, research problem, objectives and the expected outcomes of the proposed work. In addition, the outline of the thesis and a brief introduction of each chapter are provided at the end of the chapter.
