Abstract
The present invention relates to a method for manufacturing carbon conductive coating for applying on a current collector used in a lithium ion battery. The method includes providing carbon material, an adhesive, a conductive agent and an additive dissolved and dispersed in a solvent, and then mixing the adhesive, the conductive agent and the additive sequentially via ball milling and a sonication method so as to form conductive slurry. A coupling agent is added and mixed with the conductive slurry. A conductive carbon-coated current collector is prepared by coating the conductive slurry on a copper foil.
