The aqueous electrolytes are mainly used as electrolytes for supercapacitors, but there are disadvantages such as limited range of potential windows and electrolyte leakage problem. Therefore, many researchers are being held to develop electrolytes using polymers using non-aqueous electrolytes. The PVDC-g-(PMMA-g-POEM) was synthesized by ATRP and was used for supercapacitor polymer electrolyte with bis(trifluoromethane) sulfonamide lithium (LiTFSI) salt for enhancing ionic conductivity. PVDC-g-PMMA is the hydrophobic backbone which gives mechanical property that decreases crystallinity with grafting PMMA to PVDC and POEM possesses the hydrophilic side chain, making electron pathway which raises the electron transport properties. The coin cell structure with two stainless steel was used to measure ionic conductivity. Furthermore, solid-state flexible devices using carbon-based electrode are fabricated and assembled symmetrically using as-synthesized polymers as electrolyte. |
