My thesis revolves around the preparation, characterisation and then evaluation of thin
films of Vanadium Pentoxide in three Electrolytes. These films were on a glass
substrate with a thin FTO (Fluorine doped Tin Oxide) film, our precursor being Vanadium
Acetylacetonate (ACAC). The method used to create our samples was APCVD
(Atmospheric Pressure Chemical Vapour Deposition). Each sample was characterised
using Raman Spectroscopy, Energy Dispersive Spectroscopy (EDS), Scanning Electron
Microscope (SEM) and X-ray photo electron spectroscopy (XPS).
The evaluation was performed through Cyclic Voltammetry, where we observed the
behaviour of our samples in each separate electrolyte, namely Lithium, Aluminium and
Zinc. Additionally, there is a guide to install GPAW, a simulation program that uses DFT
theory which could assist in predicting and thus “perfecting” our experimental model to
yield more favourable results. Finally, we of course discuss our findings and provide
some advice moving forward
