ABSTRACT A novel dual-mode sulfur-based cathode material is prepared for the first time, in which sulfur is embedded in both the pyrolyzed PAN nanoparticles (pPAN) and mildly reduced graphene oxide nanosheets (mGO). The pPAN-S/mGO-S composite demonstrates outstanding electrochemical performances in the rechargeable Li-S batteries.
