Lower temperature operating sodium beta-alumina battery (LT-NBBs) for grid scale energy storage |
| 초록 |
The presentation introduces Korea-U.S. collaborative efforts to develop a lower temperature operating sodium beta-alumina battery (LT-NBB) with a Na/NiCl2 chemistry. Since the novel battery runs at below 200oC, it can be fabricated at an ultra low manufacturing cost by introducing a novel planar cell design with a greatly reduced number of cell components, and by eliminating expensive conventional sealing technologies. Enhanced degradation resistance of cathode materials is another important advantage of this technology. This presentation will start with stating the problems found in traditional sodium beta-alumina batteries, and possible solutions to resolve the issues will be described. Challenges and progress in materializing prototype LT-NBB cells, and related core technologies, including cell design, highly toughened solid electrolyte, enhanced wetting, and inexpensive sealing method, will be discussed. |
