| description | Supercapacitors have emerged as advanced energy storage solutions, characterized by their rapid charge–discharge abilities, elevated power density, and remarkable cycling stability. This study focuses on improving electrochemical performance of proton-conducting alginate-based biopolymer electrolytes (BBPEs) through the addition of glycolic acid (GA) and ethylene carbonate (EC) as plasticizers for potential application in symmetric supercapacitors. Two distinct systems were developed: System I, composed of alginate with GA, and System II, which further includes ethylene carbonate EC as a plasticizer. The plasticized system demonstrated a notable improvement in ionic conductivity, which led to enhanced electrochemical properties, such as a stable potential window of 1.85 V and excellent cycling stability over 10,000 cycles. The fabricated supercapacitors for System II exhibited a specific capacitance of 19.05 F g−1 and energy density of ~ 6.20 Wh kg−1, with a power density of ~ 212 W kg−1. These findings highlight the potential of alginate-based BBPEs for use in sustainable and efficient energy storage applications. |
