Subrahmanya SV, Yethadka SN, G K N. Electronic Booster PEDOT:PSS-Enriched Guar Gum as Eco-Friendly Gel Electrolyte for Supercapacitor. ACS OMEGA 2024; 9:24610-24615. [PMID: 38882079 PMCID: PMC11170695 DOI: 10.1021/acsomega.4c00786] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 05/10/2024] [Accepted: 05/16/2024] [Indexed: 06/18/2024]
Abstract
Supercapacitors based on biobased materials have been regarded as alternative portable energy storage technology for wearable or flexible electronics. Herein, we construct a unique electronic booster-imbedded biopolymer electrolyte with enhanced power density and long cycling life quasi-solid-state supercapacitor using poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) PEDOT:PSS/guar gum (GG). The eco-friendly 2% (v/v) PEDOT:PSS in the GG matrix doped with 0.05 wt % of lithium perchlorate (LiClO4) was highly flexible and showed an ionic conductivity of 10-2 S cm-1 at 323 K. The surface morphology showed unique potential wells of PEDOT:PSS boosting the nonconductive GG and interaction with activated carbon-based electrodes. As a result, a specific capacitance of 141 F g-1 at 5 mV s-1 was observed. The cyclic stability was 98% even after 1000 charge-discharge study cycles. To the best of our knowledge, this is the first work demonstrating a high-performance supercapacitor with conducting polymer-boosted guar gum as the polymer gel electrolyte, and it provides scope for understanding further stability testing and the interaction mechanism within the polymer matrix.

Abstract
Ionic liquid (IL) is now being considered as a novel contender in the development of highly conducting polymer electrolytes rather than a solvent. It has a significant impact on the electrochemical performance of polymer electrolytes. This study emphasizes the significance of low viscosity IL dispersion within a polymer (PVA) matrix. The electrical, structural and photoelectrochemical properties of the IL-doped polymer electrolyte are discussed in detail. These highly conducting IL doped solid polymer electrolytes show promise towards the development of highly efficient Supercapacitors.

Molecules 2022; 27:1993. [PMID: 35335354 PMCID: PMC8953813 DOI: 10.3390/molecules27061993] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2022] [Revised: 03/14/2022] [Accepted: 03/15/2022] [Indexed: 01/27/2023] Open
Abstract
The impact of the charge transfer complex on the dielectric relaxation processes in free poly(methyl methacrylate) (PMMA) polymer sheets was investigated. The frequency dependence of dielectric properties was obtained over the frequency range 0.1 Hz-1 MHz at temperatures ranging between 303 K and 373 K for perylene dye and acceptors (picric acid (PA) and chloranilic acid (CLA)) in an in situ PMMA polymer. The TG/dTG technique was used to investigate the thermal degradation of the synthesized polymeric sheets. Additionally, the kinetic parameters have been assessed using the Coats-Redfern relation. The dielectric relaxation spectroscopy of the synthesized polymeric sheets was analyzed in terms of complex dielectric constant, dielectric loss, electrical modulus, electrical conductivity, and Cole-Cole impedance spectroscopy. α- and β-relaxation processes were detected and discussed. The σ(ω) dispersion curves of the synthesized polymeric sheets show two distinct regions with increasing frequency. The impedance data of the synthesized polymeric sheets can be represented by the equivalent circuit (parallel RC).
