1. Background
Film capacitors store charge by means of two layers of conductive film that are sepa-
rated by a dielectric material. The charge accumulates on both
conductive film layers, yet remains separated due to the dielectric between the conduc-
tive films.
Electrolytic capacitors are composed of metal to which is added a thin layer of non-
conductive metal oxide which serves as the dielectric.
These capacitors have an inherently larger capacitance than that of standard film ca-
pacitors.
In both cases the capacitance is generated by electronic charge and therefore the power
capability of these types of capacitors is relatively high while the
energy density is much lower.
The Electrochemical Double Layer Capacitor (EDLC) or Super Capacitor is a form of
hybrid between conventional capacitors and the battery.
The electrochemical capacitor is based on the double layer phenomena
occurring between a conductive solid and a solution interphase.
The capacitance, coined the "double layer capacitance", is the result of charge separa-
tion in the interphase. On the solid electrode, electronic charge is
accumulated and in the solution counter charge is accumulated in the form of ionic
charge.
The EDLC embodies high power and high energy density (Fig. 1).
