Resumen en inglés | Pulsed laser deposition was used to grow LiCoO2 and LiMn2O4 thin films. Crystalline thin films were deposited on silicon at low substrate temperature (300 o C) using an oxygen pressure of 50 mTorr for LiCoO2 and 100 mTorr for LiMn2O4. The structure of these thin film materials was characterized by X-ray diffraction and Raman spectroscopy. The influence of target composition on the stoichiometry of the films was analyzed. Obtained polycrystalline LiCoO2 and LiMn2O4 thin films were used as cathode materials in lithium micro-batteries. Electrochemical measurements have been performed in both Li//LiCoO2 and Li//LiMn2O4 thin film cells. These cells were tested by the galvanostatic charge-discharge technique. Specific capacities as high as 195 and 120 mC/cm2 µm were achieved using LiCoO2 and LiMn2O4 thin films, respectively |
