NOVELTY - Preparing graphene loaded iron-oxide self assembled mulberry structure lithium ion battery cathode material involves dispersing the graphene oxide solid in 25-45 mL alcohol to obtain solution of 1-5 milligram/mL, then using ultrasonic generator to form the uniformly dispersed graphene oxide suspension-A. The analysis-soluble iron salt ferrous chloride is added into 5-25 mL de-ionized water, stirred and fully dissolved, then added to suspension-A to prepare mixed solution-B, and added into iron salt and oxidized graphite alkene, where the concentration of the iron salt is 0.05-0.5 mole/L. USE - Method for preparing graphene loaded iron-oxide self assembled mulberry structure lithium ion battery cathode material (claimed). ADVANTAGE - The method enables to prepare graphene loaded iron-oxide self assembled mulberry structure lithium ion battery cathode material which is esay to process in a simple and cost-effective manner, easy to realize. It realizes the iron oxide in situ growth of graphene surface. DETAILED DESCRIPTION - Preparing graphene loaded iron-oxide self assembled mulberry structure lithium ion battery cathode material involves dispersing the graphene oxide solid in 25-45 mL alcohol to obtain solution of 1-5 milligram/mL, then using ultrasonic generator to form the uniformly dispersed graphene oxide suspension-A. The analysis-soluble iron salt ferrous chloride is added into 5-25 mL de-ionized water, stirred and fully dissolved, then added to suspension-A to prepare mixed solution-B, and added into iron salt and oxidized graphite alkene, where the concentration of the iron salt is 0.05-0.5 mole/L. The mixed solution-B is put into homogeneous hydro-thermal reaction kettle, then the reaction kettle is sealed, put into homogeneous hydrothermal reactor for hydrothermal reaction at 50-150 degrees C, and after finishing reaction, naturally cooled to room temperature to obtain product-C. The product-C is washed by water and alcohol and dispersed in water to obtain product-D. The product-D is frozen to be free of liquid, then put into freeze drier for drying at 10-50 Pascal for 10-20 hours to obtain the final graphene loaded iron oxide self-assembled mulberry structure lithium ion battery cathode material.
