Production of edge-thionic acid-functionalized graphene nanoplatelets retaining graphitic layered structures for lithium ion batteries as anode materials. |
| 초록 |
Herein, we could introduce carbon disulfide (CS2) at the edges of graphene nanoplatelets (GnPs) with rich -C=S/-C-S bonds via ball-milling graphite in the presence of CS2. The resultant edge-thionic acid-functionalized GnPs (TAGnPs) exhibited a larger accessible surface area and smaller particle size than pristine graphite. Importantly, the TAGnPs retained a long-range-ordered graphitic layered structure similar to pristine graphite. When the TAGnPs are used as anode materials for LIBs, they displayed superior rate capability compared to pristine graphite and the reference edge-hydrogenated GnPs (HGnPs), which mainly have -C-H bonds at their edges. |
