Abstract

The electrochemical performance of lithium cobalt oxide (LiCoO₂) cathode materials in lithium-ion batteries is strongly influenced by their structural and chemical characteristics. Annealing in a reducing atmosphere is able to modify the crystal structure of LiCoO₂ by inducing oxygen vacancies, ideally enhancing its electrochemical performance. This master's thesis presents an investigation into the effects of low to mid-range annealing temperatures in a reducing atmosphere on bulk LiCoO₂ powder, utilizing Raman spectroscopy and X-ray Diffraction (XRD).
