摘要
CeO2 then films have been fabricated on stainless steel substrate heated at 700℃ in an oxygen ambient by pulsed laser deposition. SEM showed that as-deposited films are mainly com- posed of uniform nanocrystalline particles. Films were characterized by X-ray diffraction from which the oxygen deficient polycrystalline Ce6O11, with a modified monoclinic strUcture has been demon- strated. The electrochemical properties of the films were measured with cyclic voltammetry and galvonostatic charge /discharge techniques. Our results showed that the CeO2 film exhibits good cy- clibility with a reversible capacity of 45mC. cm-2（in the range of 0.1 to 1.5V at current density 40μA. cm-2）. It can be suggested that CeO2 thin film is suitable for the anode of Li rechargeable microbattery.

SEM showed that as-deposited films are mainly com- posed of uniform nanocrystalline particles. Films were characterized by X-ray diffraction from which the oxygen deficient polycrystalline Ce6O_(11), with a modified monoclinic strUcture has been demon- strated. The electrochemical properties of the films were measured with cyclic voltammetry and galvonostatic charge /discharge techniques. Our results showed that the CeO2 film exhibits good cy- clibility with a reversible capacity of 45mC. cm-2(in the range of 0.1 to 1.5V at current density 40μA. cm-2).
