To differentiate the fluorination of La2(Ni/Co)O4 from the conductive additive, one option is to replace carbon by other conductive materials which show higher oxidative stability. Conductive oxides could serve the purpose, since the metals contained are already oxidized to their highest oxidation state, leaving no option for further oxidation by electrochemical fluorination apart from the oxidation of lattice oxygen. Especially SnO2-based conductive oxides are prominent due to vast amounts of literature on those materials due to their application as transparent conductive oxides for touchscreens or solar cells.
