| Abstract: The electrochemical performance of SiO was investigated with galvanostatic charge-discharge cycling. The electrochemical impedance spectroscopy (EIS) using a two-electrode system in a frequency range from 0.5 MHz to 0.001 Hz was conducted on SiO electrode. Different equivalent circuits were proposed for fitting the experimental results at different voltages. According to the fitting results， the kinetic of Li-ion insertion at SiO and its evolution property of surface/interface during the first discharging operation were discussed. |
