V2O5 thin layers are electrodeposited on a stainless steel (Type 18N12Kh9T) anode from an aqueous metavanadate solution. The oxide deposits are subjected to thermal treatment at 300 or 500°C and tested in a redox reaction with lithium. The findings are compared to the behavior of similar deposits obtained from a vanadium oxysulfate solution. The use of prepared deposits in thin-film lithium batteries is discussed. The physicochemical and structural properties and surface morphology of synthesized materials are investigated using X-ray diffraction, IR absorption spectroscopy, atomic force microscopy, and thermal analysis. In comparison to coarse-grain deposits obtained in metavanadate solutions, deposits formed in vanadium oxysulfate solutions exhibit better adhesion to a substrate due to their branched structure. To use the V2O5 deposited from metavanadate solution in lithium batteries, new ways for modification of the deposit surface morphology must be developed. The coarse-grain structure of V2O5 can be broken if electrodeposition is carried out in the presence of Co2+ ions.
