what capacitors can be used as energy storage capacitors

Ultracapacitors and the Ultracapacitor Battery

However, the voltage rating of an ultracapacitor is usually less than about 3 volts so several capacitors have to be connected in series and parallel combinations to provide any useful voltage. Ultracapacitors can be used as energy storage devices similar to a battery, and in fact are classed as an ultracapacitor battery.

Capacitors store energy by holding apart pairs of opposite charges. Since a positive charge and a negative charge attract each other and naturally want to come together, when they are held a fixed distance apart (for example, by a gap of insulating material such as air), their mutual attraction stores potential energy that is released if they ...
