Supercapacitors: Principles and characterization using Autolab

Supercapacitors (also known as ultracapacitors, electrochemical capacitors, or double-layer capacitors) are electrochemical devices that have the ability to store and release charge and deliver high power densities over short periods of time. Their ability to store electrical energy efficiently and release electrical energy very quickly make them ideally suited for applications where short time backup power and peak power needs are critical.
