Electrochemical performance test of SHC-450 and HC-450 electrodes for a PIB anode. (a) The CV curves at a scan rate of 0.1 mV s−1. (b) Cycling performance of SHC-450 and HC-450 tested at a current density of 0.1 A g−1. (c) Charge–discharge profiles for SHC-450 during cycling. (d) Rate performance of SHC-450 and HC-450 at various current densities from 0.1 to 2 A g−1. (e) The corresponding charge and discharge voltage profiles of SHC-450 at different current densities. (f) Rate performance compared to other reported heteroatom-doped carbonaceous materials. (g) Cycling performance of SHC-450 and HC-450 tested at a current density of 1.0 A g−1.
