▎ 摘  要

NOVELTY - Preparation of lithium-air battery cathode catalyst doped with sulfur and nitrogen, involves step 1, mixing the raw materials containing sulfur and nitrogen with the carbon matrix in a solvent, then transferring to a closed reaction vessel, and solvothermally reacting at 150-260 degrees C to form a precursor dispersion, step 2, centrifugal washing the precursor dispersion, and vacuum drying under the protection atmosphere for high temperature cracking. USE - Preparation of lithium-air battery cathode catalyst doped with sulfur and nitrogen used in organic system, all-solid state, water system, and water/non-aqueous mixed system lithium-air battery systems. ADVANTAGE - The catalyst effectively reduces charge and discharge overpotential and improves battery cycle stability.
