Hierarchical Vine-Tree-Like Carbon Nanotube Architectures: In-Situ CVD Self-Assembly and Their Use as Robust Scaffolds for Lithium-Sulfur Batteries

Hierarchical vine-tree-like carbon nanotube architectures composed of vine-like single-walled carbon nanotubes wrapping around the tree-like multi-walled carbon nanotubes are fabricated through in-situ chemical vapor deposition self-assembly. The vine-tree-like nanoarchitectures exhibit excellent cycling stability and rate performance when employed as the cathode scaffolds for lithium-sulfur batteries.
