From Hollow Carbon Spheres to N‐Doped Hollow Porous Carbon Bowls: Rational Design of Hollow Carbon Host for Li‐S Batteries

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 capabi... View More
