Although the charging capacity is lower for the FATO-based composites, Rietveld-refinements of the charged cells reveal that similar degrees of fluorination have been achieved in both composites. For, La2CoO4 full conversion into the monoclinic fluorinated phase was achieved, as reported before by Nowroozi et al. . showing that the cathode composites prepared as described in Section 2.1.2 allow all particles of the chosen active material to participate in the electrochemical reaction and that the particle size obtained by ball-milling is sufficiently small to fully fluorinate the respective powder particles.
