dc.description.abstract	Preferred c-axis oriented LiCoO₂ thin films were prepared on the SiO₂/Si (SOS) substrates by pulsed laser deposition (PLD). Thin film electrodes without carbon and binder are ideal samples to study the electrochemical properties of materials. We did galvanostatic charge/discharge measurements between 3 and 4.7 V on the Li/LiCoO₂ cell to study its electrochemical behavior. Potentiostatic intermittent titration technique (PITT) was used to measure the Li diffusivity in the LixCoO₂ film at different Li concentrations (0.15 < x < 0.75). The dependence of Li diffusivity on the c-lattice parameter and valence of cobalt ions is discussed.	en
