摘要
Platelet- and fibrillar-structured V2O5films have been prepared by solution methods, and their electrochemical Li+intercalation properties have been studied. Platelet film consists of 20-30 nm sized V2O5particles with random orientation, whereas fibrillar film is comprised of randomly oriented fibers though most of them protrude from the substrate surface. These platelet- and fibrillar-structured films exhibit relatively larger surface area and shorter diffusion path for Li+intercalation than plain thin film structure. The processing methods, the discharge capacity, and cyclic performance of these films are compared with those of the conventional plain structured film.
