Self-Assembled Contorted Polycyclic Aromatic Hydrocarbon: Promising Li Insertion Organic Anode |
| 초록 |
Enhancing the performance of carbon-based materials in Li-ion battery (LIB) systems is of considerable interest in terms of next-generation LIB host electrodes due to the unique intercalation-de-intercalation behavior. Here, we explored the potential of a new class of contorted hexabenzocoronene (c-HBC) as a high-performance LIB system anode material. The exploitation of the polymorphic crystalline nature of c-HBC resulted in successful development of a LIB anode based on a newly found crystal phase of R-3 by THF-vapor and thermal annealing. The resulting electrochemical characteristics using Li-metal-half-cell architecture clearly reflected single-stage Li insertion behavior associated with the enhanced interspacing and short diffusion length of c-HBC molecule during the discharging process. In addition, the LIB with c-HBC anode exhibited excellent rate performance with stable cycle endurance, highlighting the suitability of c-HBC as an anode material for high-performance LIB system. |
