Abstract

LAYERED LiCoO2 was synthesized by sol-gel method using ……succinic, malic and tartaric acid as chelating agent. The delithiated LixCoO2 oxide was obtained by chemically extracting lithium from the corresponding LiCoO2 with the oxidizer K2S2O8. X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM), Transmission Electronic Microscope (TEM), Fourier Transform Infra-Red (FTIR), and Raman Scattering (RS) were used for characterization of the lithiated and delithiated phase. It shows that the samples obtained are layered LiCoO2 with the α-NaFeO2 structure. All the samples are homogenous and the particle size can be easily controlled by the preparation temperature. Upon lithium deintercalation from the host material, two different phases can be found.
