▎ 摘  要

NOVELTY - Preparing sulfur-graphene-based microporous carbon-lithium-sulfur battery anode material, comprises pouring glucose and surfactant into graphene oxide, ultrasonically treating, dissolving the glucose completely in graphene oxide, transferring to polytetrafluoroethylene lining of autoclave, hydrothermally reacting, cooling to obtain black-brown graphene-based carbon material, filtering the black-brown graphene-based carbon material, cleaning, drying, grinding to powder, mixing and grinding the powdered graphene-based carbon material with chemical activator, placing dried mixture into a tube furnace for carbonization and activating, naturally cooling to room temperature, taking out the samples, soaking in hydrochloric acid solution and filtering and washing with deionized water, drying sample, grinding and mixing graphene-based microporous carbon material with elemental sulfur, placing in a tube furnace for carbonization, naturally cooling to room temperature, and take out the sample. USE - The method is useful for preparing sulfur-graphene-based microporous carbon-lithium-sulfur battery anode material. ADVANTAGE - The obtained sulfur-graphite alkenyl microporous carbon exhibits excellent electrochemical performance as lithium-sulfur battery anode. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for sulfur-graphene-based microporous carbon-lithium-sulfur battery anode material.
