VCu_xO_y Thin Film by Magnetron Sputtering as Cathode Material for Thin Film Lithium-Ion Microbatteries

Abstract:

A Cu doped V₂O₅ film for lithium-ion batteries is prepared by magnetron sputtered using a vanadium target. Coppers are doped in varying proportions to investigate the effect of doping on the electrochemical properties. In comparison, the surface of doped samples is smooth and uniform. And the results of electrochemical tests indicate that the proper doped films (V: Cu=8: 1 by area) exhibit better cycle performance, wider voltage plateaus and higher capacity than other samples.
