▎ 摘　　要

NOVELTY - Preparing graphene conductive liquid comprises (a) uniformly mixing the expanded graphite, solvent and dispersant to obtain suspension, (b) introducing protective gas into the suspension to obtain mixed solution by pressurizing, (c) ball milling the mixed solution, (d) ultrasonically treating the dispersion and (e) concentrating the dispersion to obtain graphene conductive liquid. USE - The liquid is useful to the anode of lithium iron phosphate (claimed). ADVANTAGE - The liquid has good conductivity and low-temperature performance, the discharge capacity retention rate at 1C at 20 degrees C of 76-80%, and the discharge capacity retention rate at 20C rate is less than or equal to 95%. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene conductive liquid prepared by the above preparation method.
