Abstract:

Chemically modified carbon has attracted significant attention since our first report of its use in lithium/sulfur (Li/S) cells. Compared with traditional carbon materials, chemically modified carbon prevents the dissolution and diffusion of intermediate polysulfides. Therefore, it yields sulfur cathodes with long cycling stability, which has become the focus of current research in the field of Li/S batteries. This review summarizes the use of chemically modified carbon for highly efficient sulfur utilization and the synergistic chemical/physical trapping of sulfur species. The prospects of further developments of Li/S batteries using chemically modified carbon is also discussed.

Key words: Lithium/sulfur battery, Carbon, Chemical modification, Sulfur cathode, Shuttle effect
