제목 Synthesis of gel polymer electrolyte using epoxy monomer
초록 Recently lithium-ion battery has become an important element in field of energy storage. Also, electrolyte plays an important role in transporting lithium ions between electrodes. Liquid electrolytes have high ionic conductivity but problem is safety issues such as explosion and heat generation. relatively solid electrolytes have high safety but low ionic conductivity. Thus many studies are being conducted to improve the shortcomings. PEO structure has excellent mechanical durability and can be produced at low cost. It also has a porous pore structure that creates strong ion conduction protection, and can form a robust backbone, which has been studied a lot recently. However, when polymerized using a monomer having an epoxy structure, it has a similar shape to the PEO structure, but has a lower crystallinity, so ion transport is better. Therefore, it is expected to have high ionic conductivity, high thermal stability, and thermal properties.
