| Sumario: | Biopolymer solid electrolytes (BSEs) are emerged recently as a core part of research towards the numerous electrical appliances at the same time pushes forward to the implementation of greener solid state electrochemistry devices as well as practical promotions. Development of Li+ conducting pectin electrolytes is considered for the solid state electric double layer capacitor (EDLC) application for the first time and synthesized via solution casting approach. The performance of pectin electrolytes have been characterized by XRD, FTIR, FESEM, AC impedance, LSV, EIS and CV analysis. The obtained pectin electrolytes shows the significant conductivity of 3.44 × 10−3 Scm−1 for the additive and pectin ratio of 30 (m.wt%) pectin: 70 (m.wt%) LiBr. The same complex demonstrates the window stability of 3.78 V. Evidently, this optimal pectin: LiBr is recommended for fabrication of solid state EDLC and manifests the electrochemical capacitance of 19.04 F/g with excellent reversible performance. Based on these promising results, research on bio-macromolecular electrolytes is an advanced platform for designing robust energy storage devices especially wearable and flexible kinds. |
