Zusammenfassung:	The invention discloses a preparation method of water-based graphene composite conductive paste for a battery pole piece. The method comprises the following steps: firstly, respectively preparing water-based graphene slurry and water-based carbon nanotube slurry, and then mixing the water-based graphene slurry and the water-based carbon nanotube slurry by using a vacuum mixer to obtain the water-based graphene composite conductive slurry. The preparation method comprises the following steps: adding a dispersing agent into deionized water, fully dissolving, adding graphene powder, adding electric carbon black, and carrying out ultrasonic dispersion, water milling and screening on the solution to obtain the water-based graphene slurry. The preparation method comprises the following steps: adding a dispersing agent into deionized water, fully dissolving, adding the carbon nanotube powder, and carrying out ultrasonic dispersion, water milling and screening on the solution to obtain the water-based carbon nanotube
