Porous materials having yolk-shell structures are described. A porous material can include an elemental sulfur nanostructure, a carbon-containing porous shell with an exterior surface and an interior surface that defines and encloses a hollow space within the interior of the shell, and a polysulfide trapping agent. The elemental sulfur nanostructure is comprised in the hollow space of the carbon-containing porous shell. Methods of making and use are also described. |
