“…All biopolymer electrolytes progressively increase in the modulus value as the frequency rises due to the bulk effect. 45 The plotted graph clearly shows a hump during different temperature regions in both real and imaginary moduli from the modulus analysis data. A hump in the module portion signifies an apparent indication of functional materials in polymer electrolyte films at different temperatures.…”

The world needs sustainable energy resources with affordable, economic, and accountable sources. Consequently, energy innovation technologies are evolving toward electrochemical applications like batteries, supercapacitors, etc. The current study involves the solid blend biopolymer electrolyte (SBBE) with different compositions of sodium alginate blended with pectin via the casting technique. The characterization of the sample was tested by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, AC impedance, linear sweep voltammetry (LSV), and cyclic voltammetry (CV) analyses. Evidently, the sample NP4 (NaAlg/pectin = 60:40 wt %) has a higher conductivity of 1.26 × 10 −7 and 3.25 × 10 −6 S cm −1 at 303 and 353 K, respectively. The performances of the samples were analyzed with variations in temperature, frequency, and time responses to signify the blended nature of the electrolyte. Hence, the studied biopolymers can be constructed for electrochemical device applications.

“…A high-quality solid polymer electrolyte has a few speci cations such as strong ionic conductivity, stability, and exibility [3]. Biopolymers such as cellulose [4], starch [5], carrageenan [6], pectin [7], chitosan [8], alginate [9], and gum-based polymers [10] are made from living organisms Tamarind Gum is a polysaccharide which is extracted from the seeds of the tamarind tree and functions as a storage unit for the cell wall in seeds. About 65% of the seed components are made up of monomers of glucose, galactose, and xylose which are found in Tamarind Gum [11].…”

Solid Polymer Electrolyte (SPE) based on Tamarind Gum (TG) and Magnesium nitrate is synthesized by solution casting technique. The amorphous behaviour is observed by the X-ray Diffraction (XRD) analysis and the degree of crystallinity is calculated by XRD deconvolution spectra. The complex nature is confirmed by Fourier Transform Infrared (FTIR) analysis. Using FTIR deconvolution spectra, the percentage of free ions can be calculated. Glass transition temperature (Tg) is observed by Differential Scanning Calorimetry (DSC). The higher ionic conductivity (σ) of 1.97×10− 4 S/cm is observed for the sample with 1g of tamarind gum and 0.5g of magnesium nitrate (4 TMN). The conduction mechanism shows that sample 4 TMN obeys the Quantum Mechanical Tunnelling model (QMT) and Overlapping Large Polaron Tunnelling (OLPT) model. The prepared SPEs follow the Arrhenius behaviour, and the minimum activation energy (Ea) is observed for the sample 4 TMN as 0.207 eV. The lowest relaxation time (τ) is noticed as 3.46×10− 7 s for 4 TMN by tangent spectra. The transference number of ions (tion) is calculated by Wagner’s polarization method. The primary battery is fabricated by using the sample 4TMN and the Open Circuit Voltage (OCV) of 2.01 V is observed.
