TL;DR: In this paper, a preparation method of a foamed graphene lithium-sulfur battery positive plate is presented. But the preparation process of the positive electrode can be simplified by using a ball mill for ball-milling and then adding the mixture after the ball mill into a mixed solution of ethanol and water for ultrasonic dispersion to form a suspension liquid with the concentration of 1-20 g/L.
