▎ 摘  要

NOVELTY - Carbon composite comprises multiple carbon allotrope layers having a layered structure, and a pillar structure provided between the multiple carbon allotrope layers. The pillar structure includes molybdenum sulfide (MoSx) particles. USE - The carbon composite is useful in anode of sodium secondary battery (claimed). ADVANTAGE - The carbon composite: has a columnar structure between the carbon allotrope layers, so that the spacing between the carbon allotrope layers can be easily adjusted, improved electrochemical properties and improved crystallinity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the carbon composite, comprising preparing a carbon allotrope solution in which the carbon allotrope is dispersed, preparing a mixed solution by adding a pillar precursor material of molybdenum sulfide to the carbon allotrope solution, carrying out primary reduction of carbon allotropes by adding a reducing agent to the mixed solution, and carrying out secondary reduction by heat treatment.
