Electric Double Layer Capacitors (EDLC), Supercapacitors
Electric Double Layer Capacitors (EDLC), also known as Supercapacitors, are a new type of energy storage components with high energy density and power density. It stores charge by forming a double layer between the electrolyte and the electrode surface. Compared with conventional capacitors, supercapacitors can provide greater charge storage capacity over a wider operating voltage range. It is mainly composed of porous carbon materials as electrodes, organic or water-based electrolytes and separators. The high specific surface area of porous carbon materials provides a broad interface for charge storage. Supercapacitors have fast charging and discharging speed and long cycle life, and can maintain a high capacity retention rate even after tens of thousands of charging and discharging times.
