Plasticized green electrolyte and table salt for energy storage applications
The main purpose of this research is to construct an energy storage device using green solid polymer electrolyte and nontoxic salt, due to the rising number of microplastics in the ocean that can affect our health. Activated carbon materials were used to fabricate symmetrical electrodes. A SPE system was fabricated by solution casting with chitosan (CS) and dextran as the polymer host to accommodate sodium chloride (NaCl salt) for the ionic transport process. The maximum conductivity displayed by the CSDNCG4 system is 1.09?×?10?4 S/cm. The system exhibits non-Debye behavior, as evidenced by the depressed semicircle with its diameter below the real-axis and an asymmetrical tan?. The plasticizer boosts the ion transport parameters. Various dielectric characteristics, including dielectric loss, electric modulus and dielectric constant, are measured versus frequency. Dielectric analysis and conductivity show the same trend. Through TNM measurement, the ion fraction and its contribution were identified. The potential stability of the CS/dextran/NaCl film was found to reach 1.8 V. The capacitive behavior of the constructed EDLC was analyzed using the CV test. The Cspe was found to be 7.3 F/g at 10 mV/s.
