Super capacitors also known as electric double layer capacitors or electrochemical double layer capacitors edlcs or ultracapacitors are electrochemical capacitors that have an unusually high energy density when compared to common capacitors typically on the order of thousands of times greater than a high capacity electrolytic capacitor. Carbon is the material of choice for supercapacitor electrodes electrochemical doublelayer capacitors edlcs because it meets three important requirements needed for active materials for electrochemical energy storage applications.
