▎ 摘　　要

NOVELTY - Composite material comprises vulcanized polyaniline anode-transition metal sulfide composite material, vulcanized polyaniline anode-fast ionic conductor composite material or vulcanized polyaniline-anode conductive carbon composite material. USE - The composite material is useful in preparing lithium-sulfur battery (claimed). ADVANTAGE - The composite material: has better specific capacity, rate performance, cycle stability and discharge voltage; and preparation method utilizes readily and easily available raw materials, is simple and direct, does not require cumbersome steps and harsh experimental conditions and produces product with high yield in simple, environmentally-friendly thus suitable for commercial production. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: Preparing composite material, comprising reacting polyaniline, sublimed sulfur and transition metal compound/fast ion conductor/conductive carbon under an inert atmosphere; Lithium-sulfur battery comprising the composite material is a powder material or a self-supporting film; and Lithium-sulfur battery, prepared by comprising making the anode sheet is made of the sulfurized polyaniline composite anode material, the polyethylene or polypropylene film as a separator, the metal lithium sheet as a cathode and assembling a battery with a commercial electrolyte.
