An elastic gel polymer electrolyte fused with 1-methyl-1 propylpyrrolidinium Bis (Trifluoromethanesulfonyl) imide for solid-state lithium secondary batteries |
| 초록 |
We report the synthesis of a gel polymer electrolytes (GPE) based on the standard solution casting technique by blending poly (vinylidene fluoride-co-hexafluoropropylene) (PVdF-HFP) and lithium bis(trifluoromethanesulfonyl) imide (LiTFSI), with an ionic liquid, 1-methyl-1-propylpyrrolidinium bis(trifluoromethanesulfonyl) imide (PMPyrrTFSI). At room temperature, the GPE exhibited the highest ionic conductivity of 6.93 × 10-4S cm-1 (25 oC) with a Li transference number of 0.38 and wide electrochemical stability up to ~5.6 V. The optimized GPE also showed an outstanding thermal stability up to 420 oC. Li half cells (LiFePO4/Li metal) showed the discharge capacity of 151 mAh g-1 with a good cycling and rate capability performances at room temperature. |
