Lithium-ion batteries are secondary battery with the advantages that are high operating voltage, high energy density, no memory effect and low self-discharge. The purpose of this experiment is to make materials that can be applied to electrolyte synthesis. Fluorosulfonyl group containing material was used to synthesize a sulfonylimide chloride structure. When that structure is added to ammonia carbonate, sulfonylimide-type sulfamoyl structure is synthesized. The product was analyzed by FT-IR and 1H-NMR. As a result, we have two sulfanilamide’s structure with a chloride structure and an amine structure. These two types of sulfonylimide structures can be applied to electrolyte synthesis. In addition, sulfonylimide chloride structure is synthesized with acrylamide. Then, the product has a sulfonylimide and urea structure together. This material will make copolymers with styrene or ethylene or ether groups. Finally, we will measure the ionic conductivity by having Li-ion in the product. |
