Carbon nanotube-based cathode materials for high-performance lithium-sulfur supercapacitors |
| 초록 |
Hybrid lithium sulfur electrochemical supercapacitor, regarded as a new energy storage device, bridged the gap between lithium-sulfur batteries and supercapacitors and can deliver a high energy and power density. However, it has been confused by kinetics imbalance, since the ion intercalation/deintercalation process in the battery-like cathode is more sluggish than the non-faradaic anion adsorption/desorption process on the capacitive anode. We investigated a functionalization S/O-CNTs hybrid with characteristics of 1D structure and high surface area. In addition, this approach involved the use of a prelithiated hard carbon with high electrical conductivity and surface area as anode exhibiting anion adsorption−desorption and the electrochemical reduction and oxidation of sulfur at similar reaction rate. This research was supported by a grant from R&D Program of the Korea Railroad Research Institute. |
