Recent progress in the development of sodium sulfur batteries for large-scale energy storage applications |
| 초록 |
Sodium sulfur (NaS) batteries have received the attention as one of the promising candidates for large-scale energy storage since they utilize naturally abundant and cost-competitive elements as electrode materials and present high energy density and llong lifetime against their opponents. The NaS batteries are the system operated in the temperature over 300oC in order to acheive appropriate ionic conductance through their beta-alumina solid electrolytes (BASEs) and hold the electrode materials in a molten state to the operation. In this presentation, our recent advances on developing the sodium sulfur cells are described. The single unit cell developed results 150W/＞1,000Wh at 350oC and its lifetime is >400 cycles. |
