제목 Synthesis of In-situ gel polymer electrolyte with multi epoxy monomer and Lithium bis(fluorosulfonyl)imide(LiFSI) used by Lithium Ion batteries.
초록 Liquid lithium batteries are one of the most commercialized secondary battery batteries, and have high energy density and low temperature characteristics. Solid polymer lithium batteries have high safety at high temperatures, but have a disadvantage in that they have low ionic conductivity due to interfacial resistance due to poor adhesion between the solid electrolyte and electrodes. In-situ polymerization of a polymer electrolyte, one of the methods to secure the problems of the above two types of electrolytes, can minimize the interfacial resistance. Monomers, lithium salts, additives and solvents are mixed and then the electrolyte is polymerized under certain external conditions to obtain a gel polymer after injection into the battery cell. Our study was fabricated using an in-situ polymerization method after selecting monomers with multiple epoxies and mixing them with LiFSI. The synthesized polymer is studied by FT-IR, and the polymer thermal properties are analyzed by TGA.
