Ultracapacitors, also known as Supercapacitors, or Electric Double Layer Capacitors (EDLC’s) store energy electrostatically as opposed to batteries which store energy electrochemically. Since ultracapacitors do not rely on electrochemical reactions, they are capable of handling very rapid charge and discharge rates at high power, repeatedly. There is a limit on the amount of energy that can be stored in an individual ultracapacitor cell, the largest typical cell today stores 3.0Wh (3000F, 2.7V). However, these cells can be connected in series/parallel to meet any energy storage system size requirement, depending on space available and economic considerations.
