In this study, the polymer electrolyte based on NaCMC-PVA with varying contents of sodium salts like NaOH were prepared by using the solution casting method and were further investigated by using various characterization techniques as a solid-state electrolyte to form a solid electrochemical supercapacitor. Electrochemical properties of blend bio-polymer electrolytes. The number for ion transference was observed to be 0.79 for the sample (30 wt%) and this showed that ions cause dominant conduction. Linear sweep voltammetry was used to analyze the stability window and the oxidation and reduction peaks were studied using cyclic voltammetry. The sample was observed to have ionic conductivity of magnitude 9.85 * 10–4 S/cm and the highest stability window of ~ 1.89 V.

摘要

In this study, the polymer electrolyte based on NaCMC-PVA with varying contents of sodium salts like NaOH were prepared by using the solution casting method and were further investigated by using various characterization techniques as a solid-state electrolyte to form a solid electrochemical supercapacitor. Electrochemical properties of blend bio-polymer electrolytes. The number for ion transference was observed to be 0.79 for the sample (30 wt%) and this showed that ions cause dominant conduction. Linear sweep voltammetry was used to analyze the stability window and the oxidation and reduction peaks were studied using cyclic voltammetry. The sample was observed to have ionic conductivity of magnitude 9.85 * 10–4 S/cm and the highest stability window of ~ 1.89 V.
