Energy Storage | Applications | Capacitor Guide

Capacitors used for energy storage. Capacitors are devices which store electrical energy in the form of electrical charge accumulated on their plates. When a capacitor is connected to a power source, it accumulates energy which can be released when the capacitor is disconnected from the charging source, and in this respect they are similar to batteries.

Perspective on electrochemical capacitor energy storage

A capacitor storage system, on the other hand, is typically sized to match the kinetic energy available for capture since it can be efficiently charged in seconds and does not have cycle-life limitations. This means a capacitor storage system is often smaller in size and lower in mass than a battery system offering comparable performance.
