A novel silica‐assisted polybenzoxazine coating strategy is developed to synthesize N‐doped hollow porous carbon bowls (N‐HPCB). Due to the high specific surface area, N atom doping, and unique bowl‐like structure of N‐HPCB, the S/N‐HPCB cathode has stable cycling stability, excellent rate capability, and high volumetric energy density.
