What is a supercapacitor?
A supercapacitor is a specially designed capacitor which has a very large capacitance. Supercapacitors combine the properties of capacitors and batteries into one device. Supercapacitors have charge and discharge times comparable to those of ordinary capacitors.
What makes supercapacitors different from other capacitors?
Available in a wide range of sizes, capacitance and modular configurations, supercapacitors can cost-effectively supplement and extend battery life, or in some cases, replace batteries altogether. What makes supercapacitors different from other capacitor types are the electrodes used in these capacitors.
How long does a super capacitor last?
The life of supercapacitors will double for every 10°C decrease in temperature or voltage by 0.1V. Supercapacitors operated at room temperature can have life expectancies of several years compared to operating the capacitors at their maximum rated temperature. L1= Load life rating of the super capacitor (typically 1000 hours at rated temperature).
What is the specific power of a battery or supercapacitor?
The specific power of a battery or supercapacitor is a measure used to compare different technologies in terms of maximum power output divided by total mass of the device. Supercapacitors have a specific power 5 to 10 times greater than that of batteries.
Are supercapacitors suitable for pulse power applications?
Supercapacitors are ideally suited for pulse power applications, due to the fact the energy storage is not a chemical reaction, the charge/discharge behavior of the supercapacitor is efficient. Supercapacitors are utilized as temporary energy sources in many applications where immediate power availability may be interrupted.
What is the maximum charge voltage of a supercapacitor?
While an ordinary electrostatic capacitor may have a high maximum operating voltage, the typical maximum charge voltage of a supercapacitor lies between 2.5 and 2.7 volts. Supercapacitors are polar devices, meaning they have to be connected to the circuit the right way, just like electrolyte capacitors.

The unit of capacitance is Farad (F) which is named after M. Faraday. Farad is the capacitance unit in respect of coulomb/volt. If we say a capacitor with 1 Farad, then it will create a 1-volt potential difference between its plates depending on the 1-coulomb charge. 1 Farad is a very large value capacitor to use as a general electronic component.
