▎ 摘  要

NOVELTY - The method involves adding graphite oxide to a ball mill. The ball mill graphite oxide is added to water ultrasonic dispersed to form a suspension. Metal salt of aluminum sulfate, magnesium sulfate and aluminum chloride are added to the suspension prepared electrolyte solution. A graphite electrode and nickel foam electrode are dipped into the electrolyte, and respectively connected to positive and negative power supply poles to turn on power for electrode position reaction. The nickel foam electrode is removed. Solvent is evaporated. USE - Method for manufacturing sulfur-graphene foam composite positive electrode for use in a lithium-sulfur battery. ADVANTAGE - The method enables simplifying sulfur composite-graphene foam composite electrode manufacturing process to directly obtain lithium-sulfur battery cathode tablets, and simplifying preparation of positive electrode. The method enables effectively inhibiting shuttle effect and improving service life of lithium-sulfur battery.
