The urea structure in which fluorosulfonyl isocyanate was introduced into methacryl that was applied to lithium ion batteries with PEGDMA by photopolymerization and radical polymerization. |
| 초록 |
The methacryl has a double bond, which allows photopolymerization and radical polymerization. PEGDMA was synthesized by reacting methacroylchloride with PEG 1000, 4000, and 8000 with different molecular weights without inhibitors. The advantage of EO of PEG used is that it provides a high donor count for alkali metals, so Li ions can easily form coordination bonds with them. Longer amorphous chain segments allow for faster segment dynamics allowing for faster cation mobility. In radical polymerization, the synthesized urea structure was substituted with Li then used as a lithium salt. The advantage of this aliphatic lithium salt is that the Tg point is lower than aromatic structure, which shows high conductivity at low temperatures. In addition, the dissociation energy is lower so giving better Li ion. |
