Abstract :
C/Li2MnSiO4 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/Li2MnSiO4. The activation process of carbon coating was analyzed and the stability of carbon coating confirmed. XPS measurement was used to prove range and reversibility of electrochemical charging/discharging process. Strong influence of Li2MnSiO4 amorphization on its electronic and ionic conductivity was observed.
