NOVELTY - Preparation of anode sheet involves mixing colloidal graphene oxide with sulfur to obtain graphene oxide/sulfur mixture, ultrasonically processing foamed nickel in acetone, hydrochloric acid, deionized water and absolute ethanol, placing foamed nickel in graphene oxide/sulfur mixture, centrifuging, freeze-drying to obtain graphene oxide/sulfur/foamed nickel, carrying out electrochemical reduction reaction using graphene oxide/sulfur/foamed nickel as working electrode, rinsing working electrode with deionized water, freeze-drying to obtain electrochemically reduced graphene oxide/sulfur/foamed nickel pole sheet, heating in hydrochloric acid to etch nickel foam, rinsing with deionized water and freeze-drying. USE - Preparation of anode sheet for lithium sulfur battery. ADVANTAGE - The method enables simple preparation of anode sheet with improved quality. The anode sheet improves energy density of lithium-sulfur battery.
