▎ 摘　　要

NOVELTY - A molybdenum disulfide/graphene nano-composite material preparing method involves dispersing graphene oxide in deionized water to graphene oxide water solution. The obtained graphene oxide water solution is added with sodium thiomolybdate and elemental sulfur at 95 degrees C and allowed for reflux process to obtain solid product followed by separating using centrifugation, washing using deionized water and vacuum drying at 100-800 degrees C for 3-5 hours to obtain the finished product. USE - Method for preparing a molybdenum disulfide/graphene nano-composite material used in a lithium-sulfur battery (claimed). ADVANTAGE - The method enables preparing the composite material with porous spherical structure and increased lithium-sulfur battery property in a simple and cost-effective manner.
