METHOD FOR APPLYING GRAPHENE AS CONDUCTIVE AGENT TO ANODE SLURRY FOR LITHIUM-ION BATTERIES

摘要

A method for applying graphene as a conductive agent to anode slurry for lithium-ion batteries. The slurry is prepared from 90-97% of active substances, 1-4% of a conductive agent, and 1-5% of an adhesive by mass in steps of dispersing the adhesive, dispersing the conductive agent, and dispersing the active substances. The prepared slurry has good uniformity and excellent stability. The lithium batteries prepared by the anode slurry can significantly decrease the internal resistance of the batteries, and improve the high current discharge performance, the low temperature performance and the high current charge-discharge cycling performance of the battery.
