| titleOfInvention | Fe capable of being used for lithium ion battery cathode3O4Preparation method of/nitrogen-doped graphene material |
| abstract | The invention belongs to the technical field of material preparation, and discloses Fe capable of being used for a lithium ion battery cathode 3 O 4 A preparation method of a nitrogen-doped graphene material. Two-dimensional graphene oxide is used as a raw material, and dopamine hydrochloride is polymerized in situ under an alkaline condition to compound graphene oxide, so that the graphene compound substrate rich in electronegative groups is obtained. Then dispersing the graphene-based compound into deionized water, adding an iron salt precursor, dropwise adding alkali liquor to adjust the pH, and controlling the alkali liquor dropwise adding rate and the subsequent high-temperature treatment process conditions to realize Fe 3 O 4 The nanoparticles are uniformly loaded on the surface of the nitrogen-doped graphene. The raw materials used in the invention are rich, and the preparation method has strong controllability. The preparation method can better control Fe 3 O 4 Growing the nano particles; obtained Fe 3 O 4 Uniformly dispersing the nano particles on the surface of the graphene; with the Fe thus prepared 3 O 4 The/nitrogen-doped graphene material is used as a lithium battery negative electrode material and has excellent lithium battery performance. |
