▎ 摘　　要

NOVELTY - Composite sulfur electrode material comprises a one-dimensional carbon nanotube grown in situ on its metal site to form a two-dimensional-one-dimensional composite material with a two-dimensional sheet material as a matrix. The sulfur element is coated on the inner and outer walls of the carbon nanotubes and embedded in the gaps formed by the interlacing of the carbon nanotubes. USE - The electrode material is useful as electrode material in metal-sulfur battery i.e. lithium sulfur battery, sodium sulfur battery, potassium sulfur battery, and/or magnesium sulfur battery (claimed). ADVANTAGE - The electrode material improves its conductivity while ensuring the excellent performance of the two-dimensional layered material, facilitates electron/ion transport, provides enough space to load sulfur and ease the volume expansion during charge and discharge, and optimizes its electrochemical performance in the field of metal sulfur batteries. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the composite sulfur electrode material.
