The present disclosure relates to an electrochemical cell including an anode, a sulfur-containing cathode, a lithium-ion-containing electrolyte, and a porous carbon interlayer disposed between the anode and the cathode. The interlayer may be permeable to the electrolyte. The interlayer may be formed from a multiwall carbon nanotube (MWCNT) or a microporous carbon paper (MCP).

Porous carbon interlayer for lithium-sulfur battery

The present disclosure includes a sulfur-carbon nanotube composite comprising a sheet of carbon nanotubes and sulfur nucleated upon the carbon nanotubes, and methods for synthesizing the same. In some embodiments, the sulfur-carbon composite may further be binder-free and include a sheet of carbon nanotubes, rendering a binder and a current collector unnecessary. In other embodiments of the present disclosure, a cathode comprising the sulfur-carbon nanotube composite is disclosed. In additional embodiments of the present disclosure, batteries may include the cathodes described herein. Those batteries may achieve high rate capabilities.
