Abstract
The LixCoO2 gels are prepared using a sol-gel route from cobalt(III)acetylacetonate Co(OAc)2 and LiOH, and their structural changes with temperature are investigated using thermal gravimetric analyses, X-ray diffraction, scanning electron microscopy and Fourier transform infrared spectroscopy. The results indicate that LixCoO2 is obtained by heating the gels at temperatures as low as 673 K in air, by adding an aqueous NH4OH to enhance a decomposition of Acetylacenate. Furthermore, LixCoO2 obtained by heating the gels at 1123 K shows a multilayer of thin crystals with a well-developed 003 diffraction.
