“…Aziz et al [ 57 ] and Shukur et al [ 58 ] also reported a similar range of carboxamide and amine bands for their electrolyte systems. Lastly, the sharp peak located at (v) 900–1200 cm −1 possibly belongs to the C-O stretching which is comparable to the previous work reported by Mejenom et al [ 59 ] and Poy et al [ 60 ]. As the concentration of glycerol is increased, this band peak becomes sharper and causes a small shoulder peak to appear which also describes the interaction between the CS-MC-NH 4 NO 3 and glycerol.…”

The fabrication of energy storage EDLC in this work is achieved with the implementation of a conducting chitosan–methylcellulose–NH4NO3–glycerol polymer electrolyte system. The simple solution cast method has been used to prepare the electrolyte. The impedance of the samples was fitted with equivalent circuits to design the circuit diagram. The parameters associated with ion transport are well studied at various plasticizer concentrations. The FTIR investigation has been done on the films to detect the interaction that occurs among plasticizer and polymer electrolyte. To get more insights into ion transport parameters, the FTIR was deconvoluted. The transport properties achieved from both impedance and FTIR are discussed in detail. It was discovered that the transport parameter findings are in good agreement with both impedance and FTIR studies. A sample with high transport properties was characterized for ion dominancy and stability through the TNM and LSV investigations. The dominancy of ions in the electrolyte verified as the tion of the electrolyte is established to be 0.933 whereas it is potentially stable up to 1.87 V. The rechargeability of the EDLC is steady up to 500 cycles. The internal resistance, energy density, and power density of the EDLC at the 1st cycle are 53 ohms, 6.97 Wh/kg, and 1941 W/kg, respectively.

“…Moreover, the CH 2 scissoring and C-H bindings are responsible for the peaks seen in Figure 3 at (vi) 1422 cm −1 , (vii) 1390 cm −1 , and (viii) 1327 cm −1 , respectively [57][58][59][60]. Finally, the steep peak at (ix) 1077 cm −1 (Figure 3) could be attributable to C-O stretching, which has been observed by Mejenom and coworkers [61] and Poy and coworkers [62]. When the concentration of glycerol increases, the band peak widens, resulting in a tiny peak at 1044 cm −1 , which also reflects the interaction inside the polymer matrix.…”

The solution cast process is used to set up chitosan: dextran-based plasticized solid polymer electrolyte with high specific capacitance (228.62 F/g) at the 1st cycle. Fourier-transform infrared spectroscopy (FTIR) pattern revealed the interaction between polymers and electrolyte components. At ambient temperature, the highest conductive plasticized system (CDLG–3) achieves a maximum conductivity of 4.16 × 10−4 S cm−1. Using both FTIR and electrical impedance spectroscopy (EIS) methods, the mobility, number density, and diffusion coefficient of ions are measured, and they are found to rise as the amount of glycerol increases. Ions are the primary charge carriers, according to transference number measurement (TNM). According to linear sweep voltammetry (LSV), the CDLG-3 system’s electrochemical stability window is 2.2 V. In the preparation of electrical double layer capacitor devices, the CDLG-3 system was used. There are no Faradaic peaks on thecyclic voltammetry (CV) curve, which is virtually rectangular. Beyond the 20th cycle, the power density, energy density, and specific capacitance values from the galvanostatic charge–discharge are practically constant at 480 W/Kg, 8 Wh/Kg, and 60 F g−1, for 180 cycles.

“…Upon the addition of 25 wt.%, the semicircle starts to disappear possibly because of the enhancement of the mobility of ions via dissociation when a huge amount of dopant is introduced [21]. The appearance of the title spike at a high NH4NO3 content is attributed to a combination in a series of Rb and bulk capacitance [22].…”

In this work, alginate doped with various contents of ammonium nitrate (NH4NO3) as a solid biopolymer electrolyte (SBE) was prepared via casting by using distilled water as a solvent. Impedance studies on alginate-NH4NO3 SBE films were conducted via impedance spectroscopy. The lowest bulk resistance (Rb) showed that the maximum ionic conductivity of the sample containing 25 wt.% NH4NO3 at ambient temperature (303 K) was 5.56 × 10 −5 S cm −1 . The temperature dependence of ionic conductivity was evaluated, and results confirmed that electrolytes followed an Arrhenius behavior. The highest conducting sample was fabricated into an electrical double-layer capacitor and characterized in terms of its electrochemical properties through cyclic voltammetry (CV) and galvanostatic chargedischarge (GCD) measurement. CV analysis indicated that specific capacitance decreased as the scan rate increased. Conversely, GCD analysis showed that specific capacitance almost remained unchanged for up to 5000 cycles. AbstrakKonduktivitas Ionik dan Sifat Elektrokimia dari Elektrolit Biopolimer Berbasis Alginate -NN4NO3 untuk Aplikasi EDLC. Dalam penelitian ini, alginate yang didoping dengan variasi konsentrasi dari amonium nitrat (NH4NO3) sebagai elektrolit biopolimer padat (SBE) di-casting dengan menggunakan air sebagai pelarutnya. Studi impedansi pada lapisan tipis SBE alginate-NH4NO3 dilakukan melalui spektroskopi impedansi. Hambatan limbak terendah (Bulk Resistance, Rb) menunjukkan bahwa konduktivitas ionik maksimum sampel yang mengandung 25% NH4NO3 pada suhu ambient (303 K) adalah 5,56 × 10 ×5 S cm −1 . Hubungan antara suhu dan konduktivitas ionik dievaluasi dan hasilnya menunjukkan bahwa elektrolit mengikuti aturan Arrhenius. Sampel konduktor tertinggi difabrikasi menjadi kapasitor listrik doublelayer dan dikarakterisasi sifat elektrokimianya dengan pengukuran cyclic voltammetry (CV) dan galvanostatic chargedischarge (GCD). Analisis CV menunjukkan bahwa kapasitansi spesifik menurun ketika laju pemindaian (scan rate) meningkat. Sebaliknya, analisis GCD menunjukkan bahwa kapasitansi spesifik hampir tidak berubah hingga 5000 siklus.
