1D Sb2S3@nitrogen-doped carbon coaxial nanotubes uniformly encapsulated within 3D porous graphene aerogel for fast and stable sodium storage

The Sb2S3 anode materials with high theoretical capacity were troubled by their sluggish electrochemical kinetics and huge volume expansion in sodium-ion batteries. Herein, we firstly designed a unique Sb2S3@nitrogen-doped carbon (Sb2S3@N-C) nanotube encapsulated by porous graphene aerogel to solve the above technical barrier. The composite aerogel with ingenious structure was creatively designed by coating polydopamine (PDA) onto the Sb2S3...
