▎ 摘 要
NOVELTY - A Graphene-reinforced carbon sodium-manganese titanium phosphate coated microsphere electrode material comprises sodium manganese titanium phosphate/carbon-reduced graphene oxide. The graphene-reinforced carbon titanium manganese phosphate coated sodium microsphere electrode material has diameter of 0.2-5 mu m and carbon content of 5-10%. USE - The graphene-reinforced carbon sodium-manganese titanium phosphate coated microsphere electrode material is useful as anode active material for sodium ion battery (claimed). ADVANTAGE - The graphene-reinforced carbon sodium-manganese titanium phosphate coated microsphere electrode material is prepared by simple method and suitable for large-scale industrial production, and has improved rate performance, reversible capacity, cycle stability and yield. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation method of graphene-reinforced carbon sodium-manganese titanium phosphate coated microsphere electrode material, which involves adding carbon source, manganese acetate powder and sodium dihydrogen phosphate powder to deionized water, stirring at room temperature, then adding graphene oxide and ultrasonically dispersing, spray-drying the solution to obtain precursor, and calcining obtained precursor under certain atmosphere.
