▎ 摘　　要

NOVELTY - Sulfur anode material, comprises sulfur-containing active material, conductive agent, and agglomerant, where the agglomerant includes poly(diallyldimethylammonium nitrate) (PDDANO3), quaternary ammonium polymer containing nitrate, and the structural connection mode of sulfur-containing active material, conductive agent, and agglomerant is mixed cross-linking. USE - The sulfur anode material is useful in lithium-sulfur batteries. ADVANTAGE - The sulfur anode material improves migration capability of lithium ions, avoids rapid and uncontrollable consumption of nitrate, and improves service life of lithium-sulfur batteries. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing sulfur anode material.
