Another shortcoming of aluminum electrolytic capacitors is the fact that the electrolytes used aren''t particularly efficient conductors because conduction in electrolyte solutions is achieved through ionic, rather than electronic conduction; instead of loose electrons moving between atoms serving as the charge carriers, ions (atoms or small groups thereof that
Electric Double Layer Capacitor (EDLC) is an ultracapacitor (or supercapacitor) based on electrodes made from varieties of carbon. Electrolyte is either an aqueous solution, or an organic solution in liquid form. The electrodes are separated by a permeable separator. Carbons in these capacitors provide a large area of contact for electrode surface.

An electrolytic capacitor is a polarized capacitor whose anode or positive plate is made of a metal that forms an insulating oxide layer through anodization. This oxide layer acts as the dielectric of the capacitor. A solid, liquid, or gel electrolyte covers the surface of this oxide layer, serving as the cathode or negative plate of the capacitor.
Electrolytic capacitors use a chemical feature of some special metals, previously called "valve metals", which on contact with a particular electrolyte form a very thin insulating oxide layer on their surface by anodic oxidation which can function as a dielectric. There are three different anode metals in use for electrolytic capacitors:
There are three families of electrolytic capacitor: aluminium electrolytic capacitors, tantalum electrolytic capacitors, and niobium electrolytic capacitors. The large capacitance of electrolytic capacitors makes them particularly suitable for passing or bypassing low-frequency signals, and for storing large amounts of energy.
The cathode is typically a carbon-based layer that is coated on the dielectric layer. This layer in the electrolytic capacitor behaves as the second conductive layer. It is connected to the negative terminal of the capacitor. Other components are also present in the construction of the electrolytic capacitor:
