Electric Double Layer Capacitors (EDLC)

Electric Double Layer Capacitors (EDLCs), also known as Supercapacitors, are electrochemical capacitors designed to store and deliver electrical energy rapidly. The most well-known example of an EDLC is the JJC0E276MELZ. This particular product is an aluminum electrolytic capacitor that features a maximum capacitance of 27 Farads, a maximum voltage of 6.3V, and an insulation resistance of 30M ohms.

EDLC Application Field

EDLCs are mainly used for energy storage applications such as automotive, industrial and consumer electronics. The JJC0E276MELZ is especially suitable for storage applications due to its high capacitance and moderate voltage rating. The product is particularly suitable for high-voltage pulse applications, such as photovoltaic water pump systems, in which the pulse needs to be absorbed quickly due to the high peak output of photovoltaics.

EDLC Working Principle

EDLCs are based on electrochemical principles and work in a similar way to batteries in that they store and release electrical energy via electrochemical processes. EDLCs form an electric double layer at the surface of an electrochemically active material. An electric double layer is an arrangement of ions and electrons on the surface of the material which creates a very large but highly capacitive layer. The capacitance of the EDLC is dependant on the material used, the size and shape of the electrode plates, and the operating temperature.

Conclusion

The JJC0E276MELZ is an example of an Electric Double Layer Capacitor, or EDLC. EDLCs are electrochemical capacitors designed to store and deliver electrical energy rapidly. The product is particularly suitable for energy storage applications such as automotive, industrial and consumer electronics, and for high-voltage pulse applications such as photovoltaic water pump systems. EDLCs work on electrochemical principles, forming an electric double layer on the surface of the electrochemically active material. The capacitance of the EDLC is dependant on the material used, size and shape of the electrodes, and the operating temperature.
