NaCrO2/Coffee Waste-derived nitrogen-doped carbon composite as high-performance cathode material for sodium ion batteries |
| 초록 |
Sodium-ion batteries are promising alternatives to lithium-ion batteries for large-scale energy applications such as energy storage systems, owing to the earth-abundance and low cost of sodium resources. O3-type NaCrO2 has attracted considerable attention owing to its electrochemically active Cr3+/4+. In this study, we propose a new facile and eco-friendly method for applying nitrogen-doped carbon to NaCrO2 using coffee waste as a carbon source. The synthesized O3-type NaCrO2/coffee waste-derived N-doped carbon composite exhibits an outstanding electrochemical performance as an NIB cathode material. The sodium/composite cell achieved a 73.7% capacity retention after 500 charge/discharge cycles. The results demonstrate the potential use of coffee waste for battery materials with improved electrochemical performances. |
