▎ 摘　　要

NOVELTY - Lithium sulfur battery sulfur-based anode binder obtained by thermal crosslinking of 30-70% guar gum, xanthan gum and 1-10% conductive polymer at high temperature, is claimed. USE - Used as lithium sulfur battery sulfur-based anode binder. ADVANTAGE - The sulfur-based anode has large load and good circulation stability, and utilizes the binder solves the problems of poor conductivity and easy falling off from the pole piece of the prior art sulfur-based anode material, improves the pole piece conductivity and pole piece material bonding force, and improves the rate performance and achieves cycle stability of the high-capacity sulfur-based cathode electrode. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: Sulfur-based anode, comprising a conductive current collector and an anode membrane arranged on at least one side of the conductive current collector, where the anode comprises 80-95% sulfur-based anode material, 2-10% conductive agent and 2-10% binder; and Preparing sulfur-based anode binder, comprising mixing and dissolving the guar gum, xanthan gum and poly (3,4-ethylenedioxythiophene): polystyrene sulfonate in deionized water mass ratio to obtain the glue solution, adding the sulfur-based anode material, conductive agent into the glue solution, and adding proper amount of deionized water, stirring uniformly to obtain the anode slurry, uniformly coating the above anode on the conductive current collector, drying at 60-100℃ and high temperature cross-linking at 150-200℃.
