A facile one-pot method was established to fabricate the well-defined core–shell structured coaxial sulfur/polypyrrole tubular nanocomposites as cathodes for long-cycling Li–S batteries.
Lithium sulfide/graphene composite as high capacity cathode material is facilely obtained by one-pot pyrolysis of graphene nanoplatelet aggregates and low-cost lithium sulfate.
Graphene decorated with hetero-Co9S8–NiS sheets have abundant active sites, which can efficiently catalyze the electrochemical conversion of lithium polysulfides in Li–S battery.
Eco-friendly, multi-heteroatom-doped 3D hybrids were constructed for the first time by one-pot pyrolysis and showed excellent electrochemical performance.
