Abstract
Lithium-ion batteries have emerged as the preferred rechargeable energy storage system for vehicles and small electronics in order to help combat the environmental issues of our time. LIBs play an increasingly important role in the electrification of internal combustion engine vehicles. The performances of existing LIBs have plateaued after decades of research and development. In addition, cost and abundance of the most common battery materials, Lithium, Nickel and Cobalt, have become an issue in the world of energy storage systems. Therefore, in order to meet the increasing demand for safe and cheap energy storage, next‐generation batteries with dramatically improved electrochemical performances must be developed and this task is being done in the form of nanostructured and lithium, cobalt, and nickel-free battery materials. This thesis includes work on the design and synthesis of a novel nanostructured electrode material for future rechargeable batteries, and the researchers have achieved a certain degree of success. The novel three-dimensional nanostructures are synthesized under controlled experimental conditions, with various experimental parameters being continuously tuned and optimized. The researchers extensively characterize the as-synthesized three-dimensional nanostructures using electron microscopy (HAADF-STEM, TEM) and X-Ray diffraction (XRD). Additionally, they carried out an electrochemical evaluation of those as-synthesized nanostructures. Experimental results demonstrate improved electrochemical performances for battery applications, suggesting three-dimensional nanostructures could be a promising electrode material for next-generation and high-power rechargeable batteries. In addition to its applications in battery materials, metal oxides has also been shown to be a promising water-splitting catalyst. A three-electrode cell and electrochemical results (Linear Sweep Voltammetry) were used to show the validity of the noble metal oxyfluoride material for water-splitting applications.
