Nowadays our scientists are creating something new every day. Most of the new applications or technologies require more energy to keep their work. Progress never waits and to be frank it is getting almost impossible to be well informed. Just too much information everywhere. Sometimes we need a rest and going somewhere is not an option. For those who like spending their free time and managing to earn and test their luck, you can try 20 Bet. In order to keep it working well, we will proceed to the new types of generators.
The main feature of supercapacitors is the ability to give a large amount of energy in a very short time interval. The device is already widely used in various industries. It is possible that supercapacitors will soon replace conventional chemical batteries everywhere.

What Is a Supercapacitor?
A supercapacitor (ultracapacitor or double-layer electrochemical capacitor) is an electrochemical device, a capacitor with an organic or inorganic electrolyte, in which the “plates” are a double electric layer at the interface between the electrode and electrolyte. Functionally, it is a hybrid of a capacitor and a chemical current source.
Supercapacitors appeared relatively recently. The first device was patented by General Electric in 1957. A feature of the supercapacitor is the ability to give off a large amount of energy in a very short period of time. An ordinary capacitor is two metal plates with a dielectric layer between them. Moreover, the electrical capacitance of the capacitor directly depends on the size of the plates. Since an increase in the size of the plates led to an increase in the device itself, it was not possible to increase the capacitance for a long time.
However, a way out was nevertheless found due to the use of porous materials for the manufacture of electrodes. The surface area of the pores of a plate is made of this kind of material. It is tens of times larger than the surface area of an electrode made of ordinary metal.
Benefits
The supercapacitor very quickly accumulates a charge and also quickly gives it away. In addition, it has a number of other advantages. It has an unlimited number of charge and discharge cycles. It can store its energy with a high density. The device does not heat up, unlike energy carriers, which are based on chemical reactions. When the supercapacitor is fully charged, it simply stops taking charge. It can withstand temperatures from -50 to +85 degrees Celsius. The supercapacitor is ecologically safe and its efficiency can reach 98%.
Where Are They Used
All these advantages allow us to say that the scope of application of the supercapacitor is unlimited. They are widely used in computer devices as power sources for memory elements. In microelectronics and radio engineering, supercapacitors are used as short-term powerful current sources and uninterruptible power suppliers. Popular new hybrid vehicles today also use supercapacitors to reduce the load on the battery.
As a replacement for batteries, supercapacitors are already used in many areas.
