Electric Double Layer Capacitors (EDLC) and Supercapacitors

Electric Double Layer Capacitors (EDLC) and Supercapacitors are electric energy storage components that offer the same types of functions but have varying degrees of efficiency. In order to understand the scope of their applications, one must first understand exactly how they work.Electric Double Layer Capacitors, commonly referred to as EDLCs, are passive electronic components, which means they do not require an external power source to operate. They are widely used in low voltage applications and are most popular because of their high-energy density, low cost, and long life cycles. An EDLC is comprised of two surfaces, or two electrodes, which are separated by an insulating material or a dielectric layer. When an external electric field is applied, both surfaces become positively and negatively charged. This creates a double electric layer which creates a charge.The working principle of an EDLC is simple. When a capacitor is connected to a power source such as a battery, the capacitor is charged. When the power source is disconnected, the capacitor is then discharged. This type of capacitor is highly efficient in terms of energy storage, however, its current output is relatively low. EDLCs are typically used in applications such as back up power supplies, pulsed-power applications, low voltage circuits, energy harvesting systems, and general electrical equipment.Supercapacitors, on the other hand, are active components, which means they require an external power source to function. These capacitors are becoming increasingly popular in many power storage applications, due to their excellent discharge capabilities and their ability to provide quick bursts of power. The working principle of a supercapacitor is similar to that of an EDLC; however, it consists of two porous electrodes that are separated by a foil-like electrolyte. A high voltage is applied across the electrodes, which creates an electric field and causes the positive charge to be attracted to one side of the capacitor and the negative charge to be attracted to the other.Due to their fast charge/discharge time, high capacity, and long life, supercapacitors are quickly becoming the go-to source for many energy storage applications. These capacitors are particularly well-suited for applications such as electric cars, energy storage for wind and solar power systems, backup power supplies, and as a combination with rechargeable batteries for use in mobile devices or laptops.The KR-5R5V224-R EDLC is a radial-leaded Supercapacitor designed for high temperature operation. It has a long life of extended use, with the standing capability for thousands of charging cycles. The long-term cycling ability of this product makes it ideal for use in applications where frequent charging and discharging may be needed. It also provides high levels of stability and reliability, making it suitable for applications that depend on consistent performance. In addition to its enhanced performance capabilities, the KR-5R5V224-R EDLC also has a low equivalent series resistance (ESR), which is essential for reducing heat generation and minimising power loss. Overall, the KR-5R5V224-R EDLC is well-suited for use in many modern energy storage applications requiring high temperature capability, extended life cycles, long life, and low ESR. This type of capacitor is particularly useful in energy storage systems, such as electric cars, energy harvesting systems, and back up power supplies. In addition to the benefits it provides for energy storage, it is also rapidly becoming an essential part of other applications, due to its fast charge and discharge times, long life, and high capacity.
