Figure 4. Electrochemical performance of Si-based electrodes. (A) Voltage profiles of formation cycle; (B) Comparison of polarization resistance (R_SEI and R_ct) after one cycle; (C) The rate capability of Si anodes containing different conductive materials; (D) Long-term stability of Si anodes with SP and SP/PAM-g-CNT 4:1; (E) Cycling performance of Si anodes with varying active material content; (F) Cycling performance of Si/Gr blended anodes. SP: Super P; CNTs: carbon nanotubes; PAM-g-CNTs: polyacrylamide-grafted CNTs.
