supercapacitors

Supercapacitors are energy storage devices that can charge and discharge very quickly, unlike traditional batteries. They store energy electrostatically across two plates separated by an electrolyte, allowing rapid movement of charge. This enables them to deliver bursts of power or absorb energy swiftly, making them ideal for applications like regenerative braking in vehicles or stabilizing power supplies. While they usually hold less energy overall compared to batteries, their high power output, fast charging, and long cycle life make them valuable in various technological and industrial contexts.
