Do I need a supercapacitor?

If you need to store a reasonable amount of energy for a relatively short period of time (from a few seconds to a few minutes), you've got too much energy to store in a capacitor and you've not got time to charge a battery, a supercapacitor may be just what you need.

What is the specific energy of a supercapacitor?

For reference, petrol fuel has a specific energy of 44.4 MJ/kg or 12300Wh/kg. Although the specific energy of supercapacitors is defavorably compared with batteries, capacitors have the important advantage of the specific power.

How does energy storage affect a supercapacitor?

The simple energy calculation will fall short unless you take into account the details that impact available energy storage over the supercapacitor lifetime. In a power backup or holdup system, the energy storage medium can make up a significant percentage of the total bill of materials (BOM) cost, and often occupies the most volume.

Are supercapacitors the future of electricity?

Capacitors, on the other hand, charge almost instantly but store only tiny amounts of energy. In our electric-powered future, when we need to store and release large amounts of electricity very quickly, it's quite likely we'll turn to supercapacitors (also known as ultracapacitors) that combine the best of both worlds.
