Active Material Utilization

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.
