Electrochemical properties of the G@HMCN/S-G cathodes. a–c CV curves of G@HMCN/S-G-2.0, G@HMCN/S-G-3.5, and G@HMCN/S-G-5.0 cycled at 0.05 mV s−1; d, e Charge/discharge curves of G@HMCN/S-G-2.0 and G@HMCN/S-G-5.0 at 0.2 C; f Cycling performances of G@HMCN/S-G-2.0, G@HMCN/S-G-3.5, and G@HMCN/S-G-5.0 at 0.2 C; g, h Charge/discharge curves of G@HMCN/S-G-2.0 and G@HMCN/S-G-5.0 at various rates; i Rate capabilities of G@HMCN/S-G-2.0, G@HMCN/S-G-3.5, and G@HMCN/S-G-5.0; j Cycling performance of G@HMCN/S-G-5.0 at 1 C. The solid and hollow symbols in f, i, j represent the discharge and charge capacities, respectively
