Abstract
Supercapacitors offer a blend of battery-like energy density and capacitor-like power density, a potentially very useful component in tandem with regular batteries for both electric vehicles and grid scale energy storage devices (1). This work explores the testing of a high-performance, environmentally sustainable alternative binder for supercapacitors. the choice of binder is crucial, especially for aqueous electrolyte systems where the binder cannot be water soluble.Commonly researched binders like PTFE or PVDF (2) pose environmental and toxicity concerns, necessitating the search for more eco-friendly options. This study focuses on Ethyl Cellulose, a plant-derived polymer binder, for synthesizing activated carbon electrodes for Electrical Double Layer Capacitors (EDLCs).Through systematic experimentation, the impact of binder concentration on electrode electrochemical performance has been explored . Notably, by varying the concentration of Ethyl cellulose, The measured capacitance per gram of active material can be more than doubled. This shows the potential of Ethyl cellulose as a greener alternative binder for supercapacitors, offering both high performance and sustainability. Furthermore, testing parameters utilized for electrochemical evaluation and materials characterization are outlined , providing insights into the comprehensive assessment of electrode performance.
