Enhancements of surface functional groups and degree of graphitization in gamma irradiated activated carbon as an electrode material

Enhancements of oxygen-containing groups on the surface activated carbons (ACs) and degree graphitization in their structures allow a potential solution for development cathode materials Lithium Sulfur Batteries (LSBs). Despite two factors having been researched considerably, most applicable electrochemical performances method have not reached. Here chemical properties commercial AC terms functional were successfully improved by gamma irradiation with dose medium variations. The number its structure both found to increase after irradiation, depending strongly upon type. best performance 900 mAh/g capacity given irradiated water under experimental conditions suggested larger correlation than that graphitization, which was be maximized air.
