▎ 摘　　要

NOVELTY - Preparing reduced graphene oxide powder of lithium-ion modification, involves (a) slowly adding washed graphene oxide slurry to a lithium hydroxide solution, heating to 40-70℃, elutriating for 1.5-3 hours in a ceramic rotating instrument for modifying graphene oxide slurry with lithium-ion to obtain graphene oxide-lithium slurry, (b) homogenizing, spraying and granulating the graphene oxide-lithium slurry to obtain graphene oxide-lithium powder, and (c) reducing and drying to obtain lithium ion-modified reduced graphene oxide powder. USE - The method is useful for preparing reduced graphene oxide powder of lithium-ion modification. ADVANTAGE - The graphene conductive agent has auxiliary reinforcing effect on the lithium ion conduction, and can improve the multiplying power performance of the battery. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: graphene conductive agent; and preparing graphene conductive agent.
