A 3D conductive network with high loading Li₂S@C for high performance lithium–sulfur batteries

We have prepared an integrated CF–CB–Li₂S@C cathode with high loading Li₂S for high areal-capacity Li–S batteries. The federated conductive network and efficient carbon coating not only provide an efficient electron transport and guarantee high active material utilization but also form a durable protective shield for suppressing polysulfide dissolution.
