Capacitors are manufactured in many styles, forms, dimensions, and from a large variety of materials. They all contain at least two electrical conductors, called plates, separated by an insulating layer (dielectric). Capacitors are widely used as parts of electrical circuits in many common electrical devices.

Electrolytic capacitors are normally made from one of three different materials: aluminum, tantalum, and niobium. Aluminum is one of three metals manufacturers use for electrolytic capacitors for several reasons:
The plastic films used as the dielectric for film capacitors are polypropylene (PP), polyester (PET), polyphenylene sulfide (PPS), polyethylene naphthalate (PEN), and polytetrafluoroethylene (PTFE). Polypropylene has a market share of about 50% and polyester with about 40% are the most used film materials.
Supercapacitors can be made from different materials depending on the type of energy storage required by the application at hand and the required capacitance ranges. The electrode materials for supercapacitors can be classified into three types based on their usage for EDLCs, pseudocapacitors, and hybrid supercapacitors.
These are primarily aluminum electrolytic capacitors, and tantalum as well as some film capacitors and Class 2 ceramic capacitors. Aluminum electrolytic capacitors, the most common type for power supplies, experience shorter life expectancy at higher ripple currents.
