The Supercapacitor Advantages

The Supercapacitor Advantages

Every day brings a new technical innovations, and the demand for smaller, more portable and more functional electronics. This places pressure on power supplies to be light and small, run for long intervals of time (i.e., have a lot of energy), and meet the calls for of a number of high present loads (i.e., have a high energy capability). Simply put, these demands cannot be met by anyone portable power supply.

For decades, batteries have been the favorred storage device for portable electronics, primarily because of their ability to store energy (high energy density). However batteries take a long time to discharge and recharge, which limits their ability to deliver power. Overcoming this power deficit is tough, if not not possible, and even newer battery technologies such as lithium ion are nonetheless a poor answer for high power applications. In applications demanding high power, over-engineering the battery will rarely be the fitting resolution, and will typically lead to increased dimension, weight, and price, and/or reduced cycle life and energy. In different words, a magic bullet is hard to find.

What Makes Supercapacitors Super?
Supercapacitors mix the energy storage properties of batteries with the ability discharge characteristics of capacitors.

To achieve their energy density, they contain electrodes composed of very high surface space activated carbon, with a molecule-thin layer of electrolyte. For the reason that quantity of energy able to be stored in a capacitor is proportional to the surface area of the electrode, and inversely proportional to the hole between the electrode and the electrolyte, supercapacitors have an extremely high energy density. They're subsequently able to hold a really high electrical charge.

The high energy density derives from the fact that the energy is stored as a static charge. Unlike a battery, there isn't a chemical reaction required to charge or discharge a supercapacitor, so it will be charged and discharged very quickly (milliseconds to seconds). Similarly, and again unlike a battery, because there are not any chemical reactions going on, the cost-discharge cycle life of a supercapacitor is nearly unlimited.
