Ultracapacitors – What are they?

An ultracapacitor, also some times called a supercapacitor, is an electrical component capable of holding hundreds of times more electrical charge or energy than a standard capacitor. This characteristic makes ultracapacitors useful in devices that require relatively little current and low voltage. In some situations, an ultracapacitor can take the place of a rechargeable low-voltage electrochemical …
