Capacitors use an electric charge difference to store energy. Capacitor energy storage systems can smooth out power supply lines, removing voltage spikes and filling in voltage sags. They are particularly useful in power quality applications where the rapid charging and discharging capabilities of capacitors are crucial.

What is the difference between a battery and a capacitor?

Compared to batteries, capacitors have a lower energy density, storing less energy per unit of volume or mass. This makes them less suitable for long-duration energy storage. Another key difference is the self-discharge property: capacitors tend to lose their stored energy relatively quickly when not in use.
