As the need for lithium-ion batteries increases day by day, the demand for high-efficiency and high-capacity batteries is also increasing. Therefore, solvents and additives for electrolytes for high-efficiency, long-life batteries are being developed. Currently, commercial lithium-ion batteries use liquid electrolytes, and the liquid electrolytes have high ionic conductivity, so battery efficiency is high. A liquid electrolyte is composed of a lithium salt and a solvent. A carbonate-based solvent is used as the solvent for the electrolyte. By synthesizing a monomer containing Fluoro with a cyclic carbonate structure with high dielectric constant and flame retardancy and stability, a monomer containing a urethane group with high ionic conductivity, stability, and high reducing power is obtained. I want to sleep. The synthesized material was confirmed by FT-IR and H-NMR.
