A supercapacitor (SC), also called an ultracapacitor, is a high-capacity capacitor, with a capacitance value much higher than solid-state capacitors but with lower voltage limits. It bridges the gap between electrolytic capacitors and rechargeable batteries. It typically stores 10 to 100 times more energy per unit volume or mass than electrolytic capacitors, can accept and deliver charge much faster than b

The expression in Equation 8.4.2 8.4.2 for the energy stored in a parallel-plate capacitor is generally valid for all types of capacitors. To see this, consider any uncharged capacitor (not necessarily a parallel-plate type). At some instant, we connect it across a battery, giving it a potential difference V = q/C V = q / C between its plates.
Super-capacitor has the longest life cycle with low energy density, and it is due to not having any chemicals or chemical reactions inside the super-capacitors. Fig. 3 shows the comparison power density and the energy density of super-capacitor with other systems like a lithium-ion battery, an electrolytic capacitor, fuel cell, etc.

Our BIGCAP® Super capacitor series is characterized by reissuance to high voltage (Single super capacitor can operate in 2.8V. ), great stability in long-term operation, wide temperature range (maximum temp.: 85o C), ultralow internal resistance that applies to electric discharge of medium and large power.
Tantalum and Tantalum Polymer capacitors are suitable for energy storage applications because they are very efficient in achieving high CV. For example, for case sizes ranging from EIA 1206 (3.2mm x 1.6mm) to an EIA 2924 (7.3mm x 6.1mm), it is quite easy to achieve capacitance ratings from 100μF to 2.2mF, respectively.
Batteries and capacitors do a similar job—storing electricity—but in completely different ways. Batteries have two electrical terminals (electrodes) separated by a chemical substance called an electrolyte. When you switch on the power, chemical reactions happen involving both the electrodes and the electrolyte.
