A sulfur host cathode has been constructed by rooting bismuth oxide nanosheets into charge coupled Co/N-co-doped porous carbon nanoboxes.
We report the design of a novel 3D conductive network structure (CNTs/Co–NC) and its application as a sulfur host for Li–S batteries.
The F and N co-doped porous carbon derived from ZIF-8 is used as a membrane in Li–S batteries with enhanced capacity and cycling stability.
The sulfur content of the composite can reach 80%, and the composite has multiple adsorption for polysulfides.
