Electric Double Layer Capacitors (EDLC) and Supercapacitors are two power storage devices that offer similar characteristics but have different applications and working principles. EDLCs and supercapacitors are both increasingly being utilized in automotive and renewable energy applications due to their high energy density, low-losses, and quick charging time.The EDLCs and supercapacitors, while technically being members of the same family (electrochemical double-layer capacitors), have different operating principles and applications. This is due to their respective chemical construction and physical attributes.The DSK-3R3H703T414-HRL is an EDLC that works on the principles of ions in an electrical double layer. It utilizes an activated carbon material within its electrode, which can be configured as either a thick or thin film. The EDLC has several notable features which make it uniquely advantageous for certain applications. These include low-losses and high-power density (10-12 Wh/kg).The structure of the DSK-3R3H703T414-HRL consists of a pair of electrodes, one anion and the other cation, accompanied by a conductive material to transport the stored charge. The electrodes are connected by a separator that is the necessary component of the double layer capacitor, which creates a local cells that can be charged and discharged over again.The anion attracts the cation and vice versa, generating attraction forces between them and forming the capacitor. When DC voltage is applied via the electrodes, the electrons are deposited on the surface of the activated carbon. The electrons, as well as the negative ions from the solution, are attracted to the positively charged electrode creating a double layer where the capacitance is generated. This charge separation produces a local electric field that allows the capacitor to store energy.The DSK-3R3H703T414-HRL is suitable for many applications such as power supplies, UPS systems, energy storage systems, motor drives, robotics, motorcycle electronics, and consumer electronic products. Its highly effective two-pole structure, low-losses, and high-power density make it especially suited for power requirements in harsh and extreme environments.In comparison, Supercapacitors are electrical double-layer capacitors that are composed of activated carbon due to its excellent surface area. They work on a different physical principle than EDLCs, based on a phenomenon called ‘pseudo-capacitance’. In supercapacitors, the anion and the cation exchange charge through an electrolyte solution, instead of via an activated carbon material This pseudo-capacitance enables them to hold large amounts of charge but also to discharge them very quickly (1000-110,000 times faster than a regular battery).Supercapacitors are generally used in applications which require a high charge/discharge rate and longer lifetime than conventional lithium-ion batteries. For example, they are used in applications such as power tools, automobiles, solar energy systems, and UPS systems. In conclusion, while both the DSK-3R3H703T414-HRL EDLC and Supercapacitors are electrochemical capacitors that possess similar characteristics in terms of energy storage, they have different applications and working principles due to their different construction and operating principles. EDLC’s are ideal for applications that require a high power density and low-losses, while Supercapacitors are suited for those applications that require a large charge/discharge rate and longer lifetime.
