▎ 摘　　要

NOVELTY - Preparing antimony oxide/reduced graphene oxide nano material composition comprises dispersing the graphene oxide ultrasonic in water to form graphene oxide water dispersion, ultrasonically dispersing diantimony trioxide in alcohol solvent to form antimony oxide alcohol dispersion, and mixing the two dispersion and magnetic stirring in a sealed condition, carrying out solvent thermal reaction for 8-24 minutes at 120-180 degrees C, removing pressure, filtering and drying. USE - The antimony oxide/reducing graphene oxide nano material composition are useful as lithium ion cathode material (claimed). ADVANTAGE - The material: has excellent electrochemical performance, and development prospect.
