Description
Summary:The increasing interest in green energy storage materials for electrochemical devices with the development of bio-polymer materials as electrolytes has recently attracted significant attention. It can offer many high-value opportunities and lower costs, and is environmentally friendly. In the present work, an investigation of the correlation of Li + carrier in alginate-poly(vinyl alcohol) complexes-based solid bio-polymer electrolytes (SPE) was carried out and successfully prepared via the solution-casting method. The prepared SPE system’s immittance response properties were investigated using electrical impedance spectroscopy (EIS) at different frequencies and temperatures. The sample containing 35 wt% of LiNO 3 was the most conducting sample, with ionic conductivity at ambient temperature achieved at 3.46 S cm −1  × 10 −3  S cm −1 . The temperature-dependent ionic conduction of the SPE system shows the properties of Arrhenius where the sample is thermally activated. Based on the electrical formulism approach, it shows that the SPE system is aligned with the ionic conductivity trend and reveals non-Debye characteristics. It also shows that the results of this finding have good potential to be applied as an electrolyte for application in electrochemical devices.
