Lithium Sulfide-Carbon Composites via Aerosol Spray Pyrolysis as Cathode Materials for Lithium-Sulfur Batteries.

ABSTRACT: We demonstrate a new technique to produce lithium sulfide-carbon composite (Li₂S-C) cathodes for lithium-sulfur batteries via aerosol spray pyrolysis (ASP) followed by sulfurization. Specifically, lithium carbonate-carbon (Li₂CO₃-C) composite nanoparticles are first synthesized via ASP from aqueous solutions of sucrose and lithium salts including nitrate (LiNO₃), acetate (CH₃COOLi), and Li₂CO₃, respectively. The obtained Li₂CO₃-C composites are subsequently converted to Li₂S-C through sulfurization by reaction to H₂S. Electrochemical characterizations show excellent overall capacity and cycle stability of the Li₂S-C composites with relatively high areal
