摘要: Thin films of LiCo0 2 (0.22-1.15 μm) were prepared by oxidation metallic cobalt in molten alkali carbonates containing Li + ions. We report here the behavior thin film LiCoO cyclic voltammetry propylene carbonate solvent systems, kinetic analysis using electrochemical impedance spectroscopy (EIS), and potential step chronoamperometry (PSCA). The chemical diffusion coefficients for ions electrodes determined; D = (2.3-9.0) X 10 -12 cm /s PSCA, 0.9 -9 -2 -8 EIS.
