Figure 12. (A) Schematic illustration of the synthesis process of DSxHNC and DSxHNC/KB@PPS [ketjen black (KB)] and schematic representation of L-S battery employing the DSxHNC/KB@PPS; (B) Galvanostatic charge/discharge voltage profiles of DS₁₄₅HNC/KB@PPS at 0.2 C; (C) Cycling performances and Coulombic efficiencies of DSxHNC/KB@PPS and PPS at 0.2 C; (D) Schematic configuration of Li-S battery with NiCo₂S₄@C-modified separator; (E) Cyclic performance of the batteries assembled with NiCo₂S₄@C and other separators at 0.5 C. (A-C) are quoted with permission from Guang et al.^[256]; and (D and E) from Li et al.^[257]. DSxHNC: Double-shelled hollow N-doped porous carbon polyhedrons; PPS: polypropylene separator.
