▎ 摘　　要

NOVELTY - A nitrogen-sulfur co-doped graphene preparing method involves mixing thiourea, formaldehyde solution and graphene oxide, self-assembling at 60-100 degrees C for 6-24 hours, and allowing for heat treatment at 600-1000 degrees C for 1-6 hours to obtain the finished product. USE - Method for preparing nitrogen-sulfur co-doped graphene for use as conductive agent and adsorbent for lithium-sulfur battery. ADVANTAGE - The method enables preparing nitrogen-sulfur co-doped graphene with excellent cycle stability, in simple and easy manner.
