Energy storage capacitors can typically be found in remote or battery powered applications. Capacitors can be used to deliver peak power, reducing depth of discharge on batteries, or provide hold-up energy for memory read/write during an unexpected shut-off.
Many electronic circuits (like the one shown) are powered by batteries. Increasingly, however, engineers are looking to capacitors as another option for providing energy as needed to all or parts of such circuits. Energy can be stored in a variety of ways. When you pull back on a slingshot, energy from your muscles is stored in its elastic bands.
The first, a battery, stores energy in chemicals. Capacitors are a less common (and probably less familiar) alternative. They store energy in an electric field. In either case, the stored energy creates an electric potential. (One common name for that potential is voltage.)
Today, designers may choose ceramics or plastics as their nonconductors. A battery can store thousands of times more energy than a capacitor having the same volume. Batteries also can supply that energy in a steady, dependable stream. But sometimes they can’t provide energy as quickly as it is needed.
Unlike batteries, which store energy through chemical reactions, supercapacitors store energy electrostatically, enabling rapid charge/discharge cycles. In certain applications, this gives them a significant advantage in terms of power density, lifespan, efficiency, operating temperature range and sustainability.
