Synthesis of Li-ion Battery Gel Polymer Electrolyte Using UV Curing |
| 초록 |
Recently, such explosions and leaks of liquid electrolytes using in lithium-ion batteries lead to vast research focus on gel polymer electrolytes because they are safer than liquid electrolytes. Among them, a gel polymer electrolyte was fabricated by a monomer having a methacryl group as a functional group and having a main chain composed of polyethylene oxide, solvents, photoinitiator and lithium salts through UV-curing. The methacryl has a double bond, which occurs in photopolymerization. The advantage of EO of PEO used is that it provides a high donor count for alkali metals, so Li-ions can easily form coordination bonds with them. The advantage of this aliphatic lithium salt is that the Glass Transition point is lower than the aromatic structure, which shows high conductivity at room temperatures. Besides, the dissociation energy is lower so giving better Li-ions and increasing the TLi+ |
