Abstract

Three different cobaltites, of interest for fuel cell technology, stoichiometric LiCoO2, Li1.08CoO2and Mg-doped LiCoO2, have been investigated using neutron powder diffraction. The measurements were carried out both at room temperature and at 650 °C. The analysis of the diffraction data by means of Rietveld refinement (space group R-3 m) shows that, at the two investigated temperatures, increasing the Li content increases lattice parameter a, while both a and c increase when Mg is added. Furthermore, for the Mg-doped powder, Mg partly replaces Co in octahedral (3b) site and partly remains as MgO.
