▎ 摘　　要

NOVELTY - Graphene loaded lithium ion battery anode material preparation involves dispersing commercially available graphene oxide in 25-40 ml deionized water to prepare 1-5 mg/ml solution, and then using an ultrasonic generator to prepare uniform dispersed graphene oxide suspension. The analytically pure soluble iron salt ferric nitrate is added to 10-25 ml deionized water with stirring to prepare iron salt solution, and then added to the prepared suspension. USE - Method for preparing graphene loaded lithium ion battery anode material (claimed). ADVANTAGE - The method prepares the graphene loaded lithium ion battery anode material in a simple and cost-effective manner with improved material conductivity, electrochemical performance, enhanced battery structure stability, and enhanced battery cycle stability. DETAILED DESCRIPTION - Graphene loaded lithium ion battery anode material preparation involves dispersing commercially available graphene oxide in 25-40 ml deionized water to prepare 1-5 mg/ml solution, and then using an ultrasonic generator to prepare uniform dispersed graphene oxide suspension. The analytically pure soluble iron salt ferric nitrate is added to 10-25 ml deionized water with stirring to prepare iron salt solution, and then added to the prepared suspension. The obtained mixed solution is dispersed with an ultrasonic generator to prepare anther suspension. The prepared suspension is poured into a homogeneous hydrothermal reactor, and then sealed reactor in a homogeneous hydrothermal reactor at 50-150 degrees C to give a product. The obtained product is washed with water and alcohol to give the form product. The obtained product is freeze-dried at -20 to -50 degrees C in vacuum to give the graphene loaded lithium ion battery anode material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic X-ray diffractometer sample analysis of the prepared product. (Drawing includes non-English language text).
