Each day brings a new technical innovations, and the demand for smaller, more portable and more functional electronics. This puts pressure on power supplies 
to be light and small, run for long periods of time (i.e., have lots of energy), and meet the demands of multiple high current loads (i.e., have a high power 
capability). Simply put, these demands cannot be met by any one portable power supply.

For decades, batteries have been the preferred storage device for portable electronics, mainly because of their ability to store energy (high energy density). 
But batteries take a long time to discharge and recharge, which limits their ability to deliver power. Overcoming this power deficit is difficult, if not impossible, 
and even newer battery technologies such as lithium ion are still a poor solution for high power applications. In applications demanding high power, over-engineering the battery will rarely be the right solution, and will typically result in increased size, weight, and cost, and/or reduced cycle life and energy. 
In other words, a magic bullet is hard to find.

This power deficit is being stretched further by the explosion in the Internet of Things (IoT). These applications are usually wireless-enabled, and yet they demand ever smaller and more portable devices, with more features and functions. Wireless transmissions, even over very short distances,
 present a tremendous power challenge to the necessarily small batteries being used in IoT devices.

Supercapacitors will be a critical enabling technology for the IoT, offering a unique combination of high power and high energy, in a thin, flat and very small 
package, to improve battery performance, and in some cases, when used with an ambient energy harvesting module or rapid recharge system, replacing the 
need to use a battery at all.

What Makes Super capacitors Super?
Supercapacitors combine the energy storage properties of batteries with the power discharge characteristics of capacitors.
To achieve their energy density, they contain electrodes composed of very high surface area activated carbon, with a molecule-thin layer of electrolyte. Since the amount of energy able to be stored in a capacitor is proportional to the surface area of the electrode, and inversely 
proportional to the gap between the electrode and the electrolyte, supercapacitors have an extremely high energy density. They are therefore able to 
hold a very high electrical charge.
The high power density derives from the fact that the energy is stored as a static charge. Unlike a battery, there is no chemical reaction required to charge or 
discharge a supercapacitor, so it can be charged and discharged very quickly (milliseconds to seconds). Similarly, and again unlike a battery, because there are 
no chemical reactions going on, the charge-discharge cycle life of a supercapacitor is almost unlimited.
