Electric Double Layer Capacitor（EDLC）, Supercapacitor

XT3585-3R0567-R is an electric double layer capacitor or supercapacitor, which is quickly becoming the optimal power source for numerous applications. This article explains the application field and working principle of this particular type of electrolytic capacitor.

Application Field

XT3585-3R0567-R and other electric double layer capacitors are increasingly used in a number of applications including: consumer electronics, automotive, industrial, renewable energy, and energy storage systems. They are becoming the go to choice as power sources for these applications due to their high power density, long life cycle, and wide working temperature range. As the need for higher power densities is rising, supercapacitors are becoming preferable to ordinary batteries.

Working Principle

Electric double layer capacitors, including XT3585-3R0567-R, are an improvement on regular capacitors and operate using an entirely different principle. Inside the capacitor two metal plates are immersed into an electrolyte. The electrolyte provides ions to form two "layers": the layer of positive ions at one end and the layer of negative ions at the other. When a current is applied a charge is stored on each layer, thus effectively doubling the total amount of energy stored in the capacitor. The two layers are separable and non-conductive, so the current passing between them is limited. This ensures a greater life cycle compared to other capacitors, which eventually start to corrode and degrade with more and more charges.

Advantages

As mentioned, electric double layer capacitors, including XT3585-3R0567-R, have a number of advantages over regular capacitors and batteries. The main advantages are:

• High power density – they can store and discharge more energy per unit volume and weight than any other type of energy storage device
• High cycle life – they can be used for thousands of charge-discharge cycles without significant loss of energy capacity
• Wide temperature range – they can operate under a wide range of temperatures from -20 to 80°C
• Low cost – they are inexpensive compared to other types of energy storage devices

Conclusion

XT3585-3R0567-R is an electric double layer capacitor or supercapacitor which is quickly becoming the optimal power source for numerous applications due to its high power density, long life cycle, and wide working temperature range. It has several advantages over regular capacitors and batteries, making it an excellent choice for any application requiring an energy storage device.
