Numerous safety accidents related to Li-ion batteries often have occurred due to unstable liquid-based electrolytes. Recently, research on solid electrolyte have attracted much attention from the high stability of the material that can resolve safety issues. Polymer electrolyte has advantages of good processability, flexibility and electrochemical stability, which can be an alternative to liquid-based electrolytes among many solid electrolytes. However, the low ionic conductivity and thermal stability of polymer electrolytes are still challenging for commercialization. In this study, polymer electrolytes using in-situ polymerization are studied for improvements of ionic conductivity and thermal stability. Polymer electrolytes fabricated showed high thermal stability (~300 ℃) and decent ionic conductivity (~10-4 S cm-1) fabricated by UV-curing process. These results demonstrate the possibility of developing a thermally stable polymer electrolyte using a simple manufacturing process. |
