Solid polymer electrolytes (SPEs) for symmetrical supercapacitors are proposed herein with activated carbon as electrodes and optimized solid electrolyte membranes, which serve the separators electrolytes. We propose design of a low-cost consisting guanidinium nitrate (GuN) poly(ethylene oxide) (PEO) poly(vinylpyrrolidone) (PVP). Using solution casting approach, blended varying GuN weight percentage ratios PVP PEO prepared. On electrolytes, structural, morphological, vibrational, ionic conductivity investigated. The electrolytes’ morphology level roughness examined using an FESEM. interlinking bond formation between polymers salt is verified by FTIR measurements, indicating that ligands chemically complex. found that, up to 20 wt.% GuN, value increased (1.84 × 10−6 S/cm) increase in mobile charge carriers. Notably, PVP/PEO/20 was fabricated into solid-state supercapacitor device, delivered potential window 0 2 V, superior energy density 3.88 Wh kg−1, power 1132 W kg−1.

ABSTRACT In order to develop novel separator for lithium batteries, a series of polyvinylidene fluoride (PVDF)/polyvinylidene fluoride‐co‐hexafluoropropylene (PVDF‐HFP)/rGO composite membranes were prepared via phase inversion method. The microstructure, thermal, and mechanical performance was thoroughly examined. differential scanning calorimetry thermogravimetric analysis results indicated that the membrane with 2% rGO exhibits best thermal stability, it could be accepted as in battery. These suggest incorporation nanosheets induce more regular arrangement chain segments, leading better stability. ion permeation through evaluated by electrochemical impedance spectroscopy, indicating whole structure demonstrated most stability across various test temperatures. Additionally, increasing concentration electrolyte allows one observe information spectrum at very low frequencies is not visible concentrations. This method can overcome limitations frequency range workstation. By developing PVDF‐HFP incorporated rGO, this study addresses challenges regarding properties battery diaphragms, offering potential high‐performance material solution advancement high‐safety batteries.
