Facile Fabrication of Porous PVDF-HFP Thin Film as Separator for Lithium-Ion Batteries |
| 초록 |
Poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) membranes have been receiving attentions because of their widely potential applications in many fields. The production of PVDF-HFP membrane with highly controlled porosity in a scalable and cost-effective way is crucially necessary. In this work, we report on the fabrication of PVDF-HFP membrane by facile single-step solution-immersion dip-coating method. Herein, the porous membrane is generated based on the concept of evaporation-induce phase separation of a ternary solution which composes of polymer in a mixture of acetone and water as solvent/nonsolvent pair. The porous film showed the multi-layered honeycomb-like cellular structure. The structural morphology and porosity of the membrane can be regulated by changing solution composition or drying conditions. Gel polymer electrolytes composed of PVDF-HFP microporous membrane incorporating BMIMTFSI:LiTFSI are characterized as the electrolytes in lithium-ion batteries. |
