“…Thus, we may deduce that the addition of glycerol in the SBE is responsible for the rise in the electrochemical stability of the plasticized samples compared to the unplasticized sample. In support of this observation and the XRD patterns shown in Figure 2, there has also been some evidence that glycerol raised the amorphous structure of the electrolyte and perhaps boosted the mobility of ions at the polymer interface, as well as the electrolyte's anodic stability [67,68]. Another interesting observation is that the operating potential window of SD50 (Figure 6c) was found to be 4.49 V, which is relatively wider than for both SC0 and SC50.…”

The increased interest in the transition from liquid to solid polymer electrolytes (SPEs) has driven enormous research in the area polymer electrolyte technology. Solid biopolymer electrolytes (SBEs) are a special class of SPEs that are obtained from natural polymers. Recently, SBEs have been generating much attention because they are simple, inexpensive, and environmentally friendly. In this work, SBEs based on glycerol-plasticized methylcellulose/pectin/potassium phosphate (MC/PC/K3PO4) are investigated for their potential application in an electrochemical double-layer capacitor (EDLC). The structural, electrical, thermal, dielectric, and energy moduli of the SBEs were analyzed via X-ray diffractometry (XRD), Fourier transforms infrared spectroscopy (FTIR), electrochemical impedance spectroscopy (EIS), transference number measurement (TNM), and linear sweep voltammetry (LSV). The plasticizing effect of glycerol in the MC/PC/K3PO4/glycerol system was confirmed by the change in the intensity of the samples’ FTIR absorption bands. The broadening of the XRD peaks demonstrates that the amorphous component of SBEs increases with increasing glycerol concentration, while EIS plots demonstrate an increase in ionic conductivity with increasing plasticizer content owing to the formation of charge-transfer complexes and the expansion of amorphous domains in polymer electrolytes (PEs). The sample containing 50% glycerol has a maximal ionic conductivity of about 7.5 × 10−4 scm−1, a broad potential window of 3.99 V, and a cation transference number of 0.959 at room temperature. Using the cyclic voltammetry (CV) test, the EDLC constructed from the sample with the highest conductivity revealed a capacitive characteristic. At 5 mVs−1, a leaf-shaped profile with a specific capacitance of 57.14 Fg−1 was measured based on the CV data.

As a key component for the future high‐safety lithium batteries, solid polymer electrolyte (SPE) is gaining an attractive momentum toward large‐scale production due to their remarkable compatibility and processability with electrodes. Further, their excellent performance can be improved using the potential use of plasticizers. A deep eutectic solvent (DES) synthesized from choline chloride (ChCl) and citric acid monohydrate (CAM) demonstrates a promising plasticizer to design good SPE membranes along with poly (vinyl alcohol) (PVA). The changes in surface chemistry of PVA‐based membranes, as determined by FTIR spectroscopy, confirms the success of DES‐plasticizing effect, where detected by wavenumber shifting around main functional groups such as OH, CO, and COC. Following this, EIS characterization on electrical properties reveals the role of 30 wt‐% DES in improving the ionic conductivity with the highest ionic conductivity equivalent to 4.66 × 10−4 S cm−1 and the crystallinity index as high as 41.09%. The presence of LiClO4 and DES and significantly reduces mechanical performance, and glass transition of PVA‐based membranes, as characterized by tensile testing and differential thermal analysis/thermogravimetric analysis. Thus, the presence of DES in PVA and LiClO4 matrices could open another window for designing SPE with novel physicochemical properties.
