▎ 摘　　要

NOVELTY - The material has adding the tris buffer and dopamine hydrochloride to the graphene oxide dispersion. The filter is removed after the completion of suction filtration, and dried to obtain a membrane loaded PPG membrane. The membrane loaded with PPG membrane is immersed into a hydroiodic acid solution. The impurity-containing PPG membrane is removed after the membrane is dissolved. The membrane is then soaked in acetone and water to remove impurities. The membrane is then dried to obtain the lithium-sulfur battery organic Polymer enhanced graphene intercalation material. USE - Organic polymer-reinforced graphene intercalation material for lithium-sulfur batteries. ADVANTAGE - The intercalation material has good mechanical strength, low porosity, specific adsorption site, high surface area and good conductivity. The intercalation material can effectively inhibit the polysulfide shuttling and enhance the electrical conductivity of the pure sulfur electrode and polysulfide control of the diaphragm capacity. The intercalation material effectively improves the battery energy density. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the scanning electron microscope (SEM) image of the PG film.
