Figure 3. CV traces at the constant scan rate of 0.1 mV s-1 for six cycles for (A) Super P, (B) C65, and (C) C45 electrodes. Dashed green lines separate two voltage ranges (i.e., from 0.01 to 0.45 V and from 0.45 to 1.2 V), where SEI formation starts occurring and the ion insertion is more prominent.
