Electric Double Layer Capacitors (EDLC)

The A1030-2R5155-AP is an Electric Double Layer Capacitor (EDLC), also known as a supercap or ultracap. It is a capacitor that has a high energy density and large potential for fast charge and discharge. EDLCs are mainly used in combination with batteries in a hybrid system, providing power that is higher than that available from batteries alone as well as longer lifetimes, or in applications such as regenerative braking where extra energy needs to be stored quickly.

The A1030-2R5155-AP has a capacitance of 2.5 Farads (F) and can handle 2600 watts (W) of input power. It has an extended operational temperature range of -25 to +65 degrees Celsius and is waterproof, making it suitable for outdoor applications. This EDLC is ideal for applications such as uninterruptible power supplies (UPS), automotive engine start systems, backup lighting systems, and solar charge controllers.

An EDLC is constructed of two electrodes, one positive (the anode) and one negative (the cathode) separated by an electrolyte consisting of a polymer, gel, or liquid. The electrolyte is an ion-conducting medium which allows the transfer of charged ions between the anode and cathode. An electric field is applied to the EDLC, drawing the positively charged ions to the negative electrode while the negatively charged ions move towards the positive electrode. This creates a double-layer of electrical charges – the “double-layer” in “Electric Double Layer Capacitor” – which stores the energy in the form of an electric field.

Supercapacitors

Supercapacitors are a type of EDLC and are similar in construction and operation. Like EDLCs, supercapacitors also use two electrodes and an electrolyte to store electrical energy in an electric field. The difference is in the electrodes. While EDLCs use electrodes made of carbon or conductive polymer that are physically separated by the electrolyte, supercapacitors use electrodes made of composite materials which are more closely spaced and store energy in pseudocapacitive processes such as electric double layer capacitance and electrochemical redox reactions.

Supercapacitors offer several advantages over EDLCs. They have a much higher energy density and no hysteresis losses. They can also be charged and discharged much more quickly, making them ideal for applications such as energy harvesting and peak power applications. The A1030-2R5155-AP is an example of a supercapacitor, offering a capacitance of 2.5 Farads, a maximum input voltage of 20 volts, and a maximum input current of 130 amps.

Supercapacitors have become increasingly popular in recent years and are finding a variety of applications in electronics, automotive, power tools, renewable energy, and medical devices. They are increasingly being used as a complement or an alternative to traditional batteries in hybrid power systems.

Conclusion

The A1030-2R5155-AP is an EDLC and a type of supercapacitor. EDLCs are mainly used in combination with batteries or for applications where extra energy needs to be stored quickly. Supercapacitors offer higher energy density and faster charge and discharge times, making them ideal for energy harvesting and peak power applications. EDLCs and supercapacitors are increasingly popular in a variety of applications due to their reliable performance and long lifetimes.
