Structure and Electrochemistry of Thin-Film Oxides Grown by Laser-Pulsed Deposition

Thin films of V(2)O(5), LiCoO(2) and LiMn(2)O(4) were grown by pulsed-laser deposition in the view of their use in lithium microbatteries. Lithiated polycrystalline crystalline thin dense films grown without post-deposition annealing were formed onto substrates maintained at low temperature (300 degrees C) from a sintered composite target including Li(2)O as additive. The structural characterizations of these films have been carried out by X-ray diffraction and Raman scattering spectroscopy. The electrochemical features of thin films are investigated by cyclic voltammetry and their charge-discharge profiles in lithium microbatteries are shown.
