제목 Crosslinked sulfonylimide solid electrolytes for lithium battery.
초록 Solvent-free UV curable electrolytes can replace liquid electrolytes due to their chemical stability. We are aiming to make an electrolyte with a Li cation attached to a methacrylate monomer that can do UV curing, not a polymer electrolyte substituted with Li cations. Fluorosulfonyl isocyanate (FSO2NCO) was used to synthesize reactive FSI-type materials. This could expect a high ionic conductivity due to electron attractor effect. A polymer with a lithium cation has a hydrophilic group in the polymer matrix and can form a wide channel that smoothly moves the lithium cation. In addition, a polymer electrolyte having thermally stable properties. Isocyanate was reacted with methacrylamide and created a urea form which can make the structure to increase further portion of lithium ions. We studied the fundamental analysis and electrical analysis for Li battery. FT-IR, photo-DSC, TGA and 1H NMR spectroscopy are employed to characterize the electrolytes.
