Nonflammable Perfluoropolyether-based Crosslinked Gel Polymer Electrolytes for Lithium Batteries |
| 초록 |
Perfluoropolyether-based gel polymer electrolytes (FGPE) were prepared using both liquid state PFPE and PFPE crosslinker via simple UV curing process. Ionic conductivity of the PFPE/lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) electrolyte is firstly investigated with various LiTFSI content to find the optimum value. After preparation of FGPE with optimum electrolyte, its characteristics such as Li+ transference numbers, thermal properties, and cell performance are investigated. The ionic conductivity of the FGPE at 60 ℃ are 1.72 x 10-5 S cm-1, and the Li+ transference number is 0.53. Also, the FGPE exhibits high combustion resistance and it is thermally stable up to 175 ℃ without any weight loss. Therefore, the prepared FGPEs are acceptable for safety-enhanced lithium batteries. |
