| 제목 | “Water-in-salt” and NASICON Electrolyte-Based Na-CO2 battery |
| 초록 | Super concentrated electrolytes, referred to as “water-in-salt (WiS) electrolytes”, have been received attention due to their wide electrochemical stability window, cost-effectiveness, and non-flammability. However, the free water molecules present in WiS electrolytes prevent the use of Na-metal as the anode for Na-gas batteries. In this study, we develop a Na-CO2 battery with WiS and Na-super-ionic conductor (NASICON) electrolytes that were used as energy storage cells and CO2 gas utilization. The WiS electrolyte and NASICON separator allow us to not only expand the electrochemical window without electrolyte decomposition, but also successfully use Na metal as the anode in Na-CO2 battery. Furthermore, we introduce a nano-sized Ru catalyst to the current collector using Joule-heating method for reducing the overpotential gap. |
