Schematic illustration for the synthesis of G@HMCN. a Photo album inspired 2D yolk-shell nanostructure for the self-supporting carbon/sulfur cathode. b Two-step coating of GO with SiO2 and porous carbon precursor PB/SiO2, followed by the carbonization and etching of SiO2 to produce G@HMCN. Tetraethylorthosilicate (TEOS) was employed as the SiO2 precursor, and resorcinol (R), formaldehyde (F), and ethylenediamine (EDA), were employed as the PB precursors
