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
