The degradation of ionic conductivity in 6ScSZ and 3YSZ SOFC electrolytes was analysed via X-ray diffraction (XRD), 4-point conductivity and electrochemical impedance spectroscopy (EIS) and the results present a consistent story: in 6ScSZ subtle but reproducible changes to the phase assembly in the form of a shrinking “cubic shoulder” are obtained with ageing at 900°C, which closely corresponds to...
C/Li 2 MnSiO 4 nanocomposite material obtained by sol–gel synthesis was studied in initial charge/discharge cycle. Electrochemical impedance spectroscopy (EIS) analysis in different states of charge (SOC) allowed to describe changes in electrochemical properties of C/Li 2 MnSiO 4 . The activation process of carbon coating was analyzed and the stability of carbon coating...
