▎ 摘 要
NOVELTY - An electrode material for a lithium-ion battery is produced by combining an electrode precursor material and humic acid (14) in an alkaline slurry (44); drying the alkaline slurry to produce a powder of humic acid-coated electrode precursor material; and heating the powder (48) to produce the electrode material comprising graphene-coated particles. USE - Production of electrode material for forming a lithium-ion battery (claimed). ADVANTAGE - Graphene can be incorporated into electrode materials to greatly improve the performance of lithium-ion batteries (LIB) by increasing conductivity and improving cycling stability and low-temperature performance. The graphene-coated cathode materials show improvement in electrochemical performance over conventional cathode materials that have amorphous carbon coatings and show superior coating uniformity and consistency in manufacture over methods using graphene or graphene oxide as the starting carbon source. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for forming an electrode of a lithium-ion battery which involves forming an electrode material; and applying the electrode material to a current collecting foil to form the electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram of the method for producing a graphene-coated electrode material using the high purity humic acid for lithium-ion batteries. 14Humic acid 42Mixing element 44Slurry 46Drying element 48Powder
