Preparation of Thermally Stable and Nonflammable Gel Polymer Electrolytes based on Perfluoropolyether for Lithium Batteries |
| 초록 |
A gel polymer electrolyte (FGPE) based on perfluoropolyether (PFPE) was prepared using PFPE crosslinker via photo-initiated polymerization. The ionic conductivity and Li ion transference number of the prepared electrolyte are 1.72 x 10-5 S cm-1 and 0.53 at 60 oC. The FGPE has high thermal stability, without any weight loss up to 175 oC, and nonflammability. Moreover, the FGPE shows an excellent electrochemical stability (up to 5.0 V vs. Li/Li+). As a result, the FGPE is expected to be suitable electrolyte for safety-enhanced high-temperature lithium batteries. |
