The volumetric and areal capacities of G@HMCN/S-G. a Schematic illustration for the advantages of electrode design; b–d the cross-section SEM images of G@HMCN/S-G-2.0, G@HMCN/S-G-3.5, and G@HMCN/S-G-5.0; e the volumetric capacities of G@HMCN/S-G-2.0, G@HMCN/S-G-3.5, and G@HMCN/S-G-5.0 after 50 cycles at 0.2 C, f the areal capacities of G@HMCN/S-G-5.0, G@HMCN/S-G-7.5, and G@HMCN/S-G-10 at 0.1 C. The solid and hollow symbols in f represent the discharge and charge capacities, respectively. Scale bars, 10 μm b–d
