XPS study of thin films of titanium oxysulfides

In this study thin films of titanium oxysulfides which could be used as positive electrode materials in microbatteries were analysed by XPS. In light of the binding energies obtained for reference compounds (different titanium oxides and Sulfides) the results have shown the existence of a new type of titanium. It presents an environment with S2−2 pairs, S2− and O2− ions, this latter in a proportion half that of sulfur ions.
