Innovative Organic Electrolytes for Enhanced Energy Density and Performance in Supercapacitors

Supercapacitors, known for their high-power energy storage capabilities, have garnered significant attention due to their rapid charge–discharge cycles and extended life span. To expand their application in fields such as electric vehicles, renewable energy systems, and portable electronic devices, the development of advanced electrolytes that can boost energy density, power density, and overall performance is crucial. This study introduces a novel electrolyte formulation comprising lithium chloride in ethylene glycol and Magnesium Acetate in methanol. These formulations are designed to address existing challenges and enhance supercapacitor efficiency. The study reports impressive specific capacitance values (Csp = 582, 360, and 224 F/g), specific energy (SE = 323, 200, and 124 Wh/kg), and specific power (SP = 11 628, 7200, and 1322 W/kg) for lithium chloride, magnesium acetate, and zinc chloride electrolytes, respectively. These findings open new avenues for developing optimal and sustainable energy storage solutions in an increasingly electrified world. Continued research in this domain is expected to unlock the full potential of supercapacitors, contributing to a cleaner and more energy-efficient future.
