▎ 摘  要

NOVELTY - An positive electrode comprises a current collector and a positive electrode active material layer arranged on at least one surface of the current collector. The positive active material layer includes a positive active material and an additive. The positive active material includes a sulfur-carbon composite. The additive includes a thiuram sulfide-based compound. USE - Positive electrode used for lithium-sulfur battery (claimed). Uses include but are not limited to portable electronic device, communication device, electric vehicles, hybrid electric vehicle, plug-in electric vehicles, electric scooters, electric golf carts and electric storage system. ADVANTAGE - The positive electrode provides the lithium-sulfur battery having excellent electrochemical reactivity, high capacity characteristics and high energy density. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a lithium-sulfur battery, which comprises the positive electrode and an electrolyte.
