High energy density, fast charge-discharge capability, long cycle life, environmental friendliness, and safety are crucial factors for the effective use of
energy storage systems. The polymer poly(3,4-ethylenedioxythiophene) (PEDOT), commonly used in wearable energy storage materials, exhibits limited
performance due to its low energy density in small portable forms [1-2]. The primary causes of low capacity are inadequate surface properties and the
inability to fully express theoretical capacity values. To overcome these performance limitations, it is necessary to improve the morphological and
chemical properties of the electrode material [3-4].
In this study, PEDOT polymer was synthesized on the surface of carbon fabric electrodes using a hydrothermal synthesis method. The polymer was
optimized by adding cobalt salts in different ratios, achieving the highest discharge time. Additionally, carbon quantum dots produced from tomatoes were
used, and the contribution ratio was optimized to enhance the material’s conductivity, surface area, and electrochemical stability. The electrochemical
performance of the produced fabric electrodes was evaluated using cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), and electrochemical
impedance spectroscopy (EIS). Structural and morphological characterizations were conducted using FTIR, SEM, and UV-Vis spectrophotometry. By
considering the low cost of the single-step manufacturing process, waste utilization, and performing reactions in a water-based environment, materials that
can offer long-term and sustainable solutions were designed for wearable electronics.
