A supercapacitor, surpassing traditional capacitors in capacitance, serves as a high-efficiency energy storage device. It utilizes the electrical double layer formation between electrode and electrolyte for charge storage, enabling swift charge and discharge cycles without relying on chemical reactions.
This mechanism facilitates its use in automotive energy recovery systems, as backup power in industrial equipment, and as auxiliary power for household electronics. Comprising porous material electrodes and an ion-rich electrolyte, supercapacitors stand out for their quick energy transfer capabilities.
Distinguished by their rapid charging/discharging, durability, safety, and minimal environmental footprint, supercapacitors are evaluated based on capacitance, voltage rating, output current, and environmental adaptability for optimal selection.
