**Main Uses** ■ Energy Recovery Electric double-layer capacitors are used to recover and store braking energy from electric vehicles and hybrid cars for later reuse. They are effective due to their rapid charge and discharge capabilities. ■ Energy Storage They are used to absorb power fluctuations from renewable energy sources and maintain a constant output, thereby improving the stability of the power network. ■ Peak Shaving They are used to supply power during peak demand times and to flatten power demand. This enhances the stability of power supply and can reduce electricity costs. ■ Energy Storage Devices In energy storage systems for homes and businesses, electric double-layer capacitors can rapidly charge and discharge, making them suitable for peak shaving and backup power sources. ■ Engine Starters They are used in internal combustion engine vehicles, such as cars, to temporarily supply large amounts of power during engine startup. ■ Power Quality Improvement They are used to improve power quality and stabilize voltage within the power network.
