What is EDLC?
In general, capacitors have an insulating material, known as a dielectric, between two opposing electrodes.
However, EDLC operates without a conventional dielectric. Instead, it leverages a physical mechanism to create a double-layer structure with dielectric-like properties. This is why it is referred to as a double-layer capacitor. The charging and discharging process in double-layer capacitors occurs through an ion-absorption layer formed on the surfaces of the positive and negative electrodes, utilizing a phenomenon known as adsorption and desorption.
These supercapacitors boast an energy density that is 8 to 10 times higher than that of EDLC (Electrochemical Double Layer Capacitors). They can withstand voltages of up to 4.2V, providing superior safety and longevity compared to traditional batteries. Furthermore, they operate within a broader temperature range.
Their primary applications span across various industries, including: Smart meters, Electronic Toll Collection (ETC) systems, Automotive auxiliary power sources, Cameras, E-cigarettes, Communication devices, Smart homes, Internet data storage, Fax machines, Lithium-ion battery balancing in parallel, Wireless mice, Streetlights, Medical equipment, Industrial sensors, Industrial equipment backup power supplies.
