1. What is an electric double-layer capacitor?

Super capacitor is also called electric double layer capacitor. It consists of two plates, and an electric field is generated between the two plates.

Its main advantage is fast charging and discharging, and has a very large capacitance (usually within the Farad range), so it can be used in electric vehicles such as Tesla cars because of its performance speed and so on.

2. What is the use of electric double layer capacitors?

Electric double layer capacitors (EDLC) are widely used. They can be used as a power balance power supply for lifting devices, which can provide super-large current power; they ca be use as a vehicle starting power source, because their starting efficiency and reliability are higher than traditional batteries, and they can fully or partially replace traditional batteries; they ca be used as a traction energy source for vehicles; they can be used in the military to ensure the smooth start of tanks, armored vehicles and other tanks (especially in the cold winter), as a pulse energy for laser weapons. In addition, they can also be used as energy storage energy for other electromechanical equipment.

3. What is an electric double-layer capacitor?

Electric Double-layer Capacitor is a kind of supercapacitors, which is a new type of energy storage device.

The electric double-layer capacitor is between the battery and the capacitor, and its extremely large capacity can be used as a battery.

Compared with batteries using electrochemical principles, electric double-layer capacitors do not involve material changes at all in the charging and discharging process, so they have the characteristics of short charging time, long service life, good temperature characteristics, energy saving and environmental protection.

Electric double layer capacitors have extremely small electric double layer spacing, resulting in weak withstand voltage, generally not exceeding 20V, so they are usually used as energy storage elements in low-voltage DC or low-frequency applications.

4. What are the advantages and disadvantages of super capacitors?

Compared with traditional batteries, supercapacitors have many advantages: fast charging speed, which can be charged to more than 95% of its rated capacity in 10 seconds to 10 minutes; power density can reach as high as (102~104) W/kg, which is 10 times that of lithium batteries. It has a high discharge capacity of high current; it can be used for 100,000 to 500,000 cycles and has a long service life; it has a high safety factor and is maintenance-free for long-term use. However, compared with mainstream sulfur batteries, it still faces the disadvantages of high cost and low energy density.

5. What is a super capacitor?

Supercapacitors can also be called large-capacity capacitors, energy storage capacitors, gold capacitors, electric double layer capacitors or farad capacitors. They mainly rely on electric double layers and redox pseudocapacitors to store electrical energy. There is no chemical reaction in the energy storage process so this energy storage process is reversible, and it is precisely because of this the supercapacitor can be repeatedly charged and discharged hundreds of thousands of times.

6. Why is supercapacitor an upgrade of traditional capacitors?

Flat capacitors are composed of two metal electrode plates insulated from each other. The capacitance is proportional to the area of the electrode plates and inversely proportional to the size of the gap between the electrode plates. The structure of a supercapacitor is similar to that of a flat capacitor. Its electrodes are porous carbon-based materials. The porous structure of the material allows it to have a surface area of several thousand square meters per gram of weight. The distance between the capacitor and the charge is determined by the size of the ions in the electrolyte. The huge surface area combined with the very small distance between the charges enables the supercapacitors to have a large capacity. The capacity of the supercapacitors can range from 1 farad to several thousand farads.

8. When the temperature of the super capacitor is too high, will its capacity decrease?

The normal working temperature of energy supercapacitors is -25℃-70℃, and the normal working temperature of power supercapacitors is -40℃-60℃. Temperature and voltage have an impact on the life of supercapacitors. Generally speaking, every time the ambient temperature of a supercapacitor increases by 10°C, the lifespan of the supercapacitor will be shortened by half. That is to say, when possible, use supercapacitors at the lowest temperature as much as possible, then the attenuation of the capacitor and the increase of ESR can be reduced. If it is lower than the normal room temperature environment, the voltage can be reduced to offset the negative impact of high temperature on the capacitor.

9. Why is a super capacitor with a large capacity but a small withstand voltage?

The capacitance of the capacitor depends on the area of the positive and negative electrode plates of the capacitor and the thickness of the insulating layer of the plates. Capacitors and batteries are essentially different. Capacitors rely on large-area plates to store charges, and the positive and negative plates need to be insulated and isolated. The thickness of the insulating layer directly affects the electric field strength of the positive and negative plates. The thinner the plate insulating layer, the stronger the electric field. The stronger the capacity of the plate to store charge, the more power it can store. But the plate insulation layer is too thin, and it is easy to break down when the voltage rises, so the withstand voltage of the capacitor tend to be small.
