Polymerization of monomers containing acryloyl group and fluorosulfonylimide structure for solid-state Electrolytes |
| 초록 |
Solid-state electrolytes, also called polymer electrolytes, are one of electrolyte types of lithium batteries. It is more stable and safe than liquid electrolyte, but has a low ionic conductivity. So, we improved the ionic conductivity by directly substituting lithium-ion in the polymer. Sulfonylimide group of monomers has F more stable than CF3. Monomers base on fluorosulfonylimide can radical reaction in acryloyl group. The polymerization in water initiator is ammonium persulfate (APS). That is accelerated by N, N, N', N'-tetramethylethylenediamine (TMEDA). The polymer is dissolved in DMSO and then made a film in IR. Also the monomers are copolymerized with acrylonitrile to make a more flexible film. The experimental results were confirmed by NMR. Finally, the film was analyzed for, TGA, DSC and ion conductivity. |
