Recently, the liquid electrolyte used in lithium ion batteries is flammable and volatile, so explosion and leakage occur at high temperatures, so research on gel polymer electrolytes, which are safer than liquid electrolytes, is being actively conducted. Among them, a gel polymer electrolyte was fabricated by a monomer having a methacryl group as a functional group, solvents, photoinitiator and lithium salts through UV-curing. The methacryl has a double bond, which occurs in photopolymerization. In addition, the methacryl group is often used because it has good photochemical reactivity after the acryl group. 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+ |
