0 a very powerful type of capacitor (= a device that collects and stores electricity, and is an important part of electronic equipment such as televisions and radios):
Supercapacitors are more powerful cousins of the basic capacitor.
This is the only supercapacitor that meets today's energy harvesting expectations.
A number of companies are developing electric double-layer supercapacitor technology.
A supercapacitor with relatively low capacitance recovers brake energy to power the electric motor when accelerating from a stop.
The amount of energy stored in a supercapacitor is called specific energy.
A battery or supercapacitor pack, or a combination of the two, can be used to store excess charge.
It can be also used as active material in supercapacitor because has very high charge transfer capability.
The following table compares the major parameters of the three main supercapacitor families with electrolytic capacitors and batteries.
