Titanium dioxide thin film with a thickness of few microns was deposited on ITO/glass by spray pyrolysis of peroxo-tiatanium complex solution as precursor. The deposited TiO2 thin film was investigated for lithium ion intercalation/deintercalation behavior in organic solvent containing lithium ions and subsequently tested for anode material in thin film lithium ion battery. Thin film battery constructed with TiO2 film as anode and LiCoOx as cathode has shown a discharge capacity of around 65 mA h g(-1) at an average cell voltage of around 2 V.
