| Abstract | The slow dissolution of lithiated-NiO cathodes in molten carbonates is the main obstacle for the commercialization of molten carbonate fuel cells. The aim of the present work was to investigate the possibility of producing an electrode based on LiCoO2. The LixCoO2 powder samples (0.8 < x < 1.1) were obtained by thermal decomposition of carbonate, acetate and oxide precursors, in air. The syntheses were monitored by thermal analysis (TGA, DTA). The calcined and sintered powder samples were characterized by X-ray diffraction and atomic absorption spectroscopy The porous electrodes were prepared with different pore-formers by cold pressing and sintering. A bi-modal pore size distribution was observed in all the materials. Conductivity measurements were carried out in the temperature range 500-700°C. The solubility in molten carbonates was measured. To test the cathodic performance of the materials under study, electrochemical impedance spectroscopy measurements were carried out to investigate the porous electrode/molten carbonate interface.
