Abstract

A free-standing electrically conductive porous structure suitable to be used as a cathode of a battery, including an electrically conductive porous substrate with sulfur diffused into the electrically conductive porous substrate to create a substantially uniform layer of sulfur on a surface of the electrically conductive porous substrate. The free-standing electrically conductive porous structure has a high performance when used in a rechargeable battery. A method of manufacturing the electrically conductive porous structure is also provided.
