Electrolytic Capacitors

Electrolytic capacitors differ from other capacitors. One of the plates in an electrolytic capacitor is a liquid. 
The liquid is an electrolyte (an ion bearing liquid that conducts electricity, which is what gives the electrolytic capacitor its name. 
During the manufacturing process, a thin layer of oxide builds up between the electrolyte and the plate. 
This thin layer of oxide forms the insulating dielectric. Because the plates are large and the dielectric is thin, the capacity to store electricity is larger in electrolytic capacitors than in any other type. 
This makes electrolytic capacitors the capacitor of choice when building power supplies.

Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors have an aluminum plate and the dielectric is aluminum oxide. 
This type of electrolytic capacitor is inexpensive and is found in many power supplies. 
Their range in value from 1 farad down to less than a microfarad. E-caps can work voltages up to several hundred volts. 
Aluminum electrolytic capacitors can break down if they go through long periods of no power (the oxide breaks down.) 
Elco caps can be rejuvenated if connected to a power supply and a resistor--the long low current restores the oxide.
Elco caps are not suitable for working with high frequencies, and they're also used in radio frequency amplifiers or anywhere there are high currents and low frequencies.

The electrolytic capacitor has been in use for many years. Its history can be traced back to the very early days or radio around the time when the first broadcasts of entertainment were being made. At the time, valve wireless sets were very expensive, and they had to run from batteries. 
However with the development of the indirectly heated valve or vacuum tube it became possible to use AC mains power.

While it was fine for the heaters to run from an AC supply, the anode supply needed to be rectified and smoothed to prevent mains hum appearing on the audio. 
In order to be able to use a capacitor that was not too large Julius Lilienfield who was heavily involved in developing wireless sets for domestic use was able to develop the electrolytic capacitor, allowing a component with sufficiently high capacitance but reasonable size to be used in the wireless sets of the day.

Electrolytic capacitor symbols

The electrolytic capacitor is a form of polarised capacitor. The electrolytic circuit symbol indicates the polarity as it is essential to ensure that the capacitor is fitted into the circuit correctly and is not reverse biased.

Circuit symbols used for polarised capacitors like the electrolytic capacitor

There is a variety of schematic symbols used for electrolytic capacitors. The first one '1' is the version that tends to be used in European circuit diagrams, while '2' is used in many US schematics, and '3' may be seen on some older schematics. Some schematic diagrams do not print the "+" adjacent to the symbol where it is already obvious which plate is which.
