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.

Supercapacitors, also known as ultracapacitors and electric double layer capacitors (EDLC), are capacitors with capacitance values greater than any other capacitor type available today. Supercapacitors are breakthrough energy storage and delivery devices that offer millions of times more capacitance than traditional capacitors.
Electrolytic capacitors, shown schematically in Fig. 3 (b), use a thinner and higher dielectric constant dielectric that is grown on a strong metal surface such as etched aluminium. These can store 10-times more energy than the electrostatic capacitors. These capacitors can generally be used up to ∼20 kHz.. It has long been accepted that
Electrical double-layer (EDL) capacitors, also known as supercapacitors, are promising for energy storage when high power density, high cycle efficiency and long cycle life are required.
Electric double-layer capacitors (now supercapacitors) were invented in 1957 when H. Becker developed a "Low voltage electrolytic capacitor with porous carbon electrodes". [17] [18] [19] He believed that the energy was stored as a charge in the carbon pores used in his capacitor as in the pores of the etched foils of electrolytic capacitors.

3. Electrochemical capacitor background. The concept of storing energy in the electric double layer that is formed at the interface between an electrolyte and a solid has been known since the 1800s.

Electrochemical capacitors (supercapacitors) consist of two electrodes separated by an ion-permeable membrane (separator), and an electrolyte ionically connecting both electrodes. When the electrodes are polarized by an applied voltage, ions in the electrolyte form electric double layers of opposite polarity to the electrode''s polarity. For example, positively polarized electrode

Electrochemical double-layer capacitors (EDLCs) are devices allowing the storage or production of electricity.

Capacitor as energy storage device. A capacitor keeps energy in the form of an electric charge. It is constructed by two metal plates, separated by an insulating material called dielectric [28]. The total energy stored is 0.5 CV 2, where C is the value of the capacitor, and V is the corresponding voltage between the two conducting plates.
An important related class of energy storage devices are pseudocapacitors, which undergo electron transfer reactions but behave like capacitors. These materials store energy through highly reversible surface redox (faradic) reactions in addition to the electric double-layer storage. Materials that exhibit such
Thinness of the double layer and exceptionally high specific surface area (∼3000m 2 g-1) enables these devices to have very high specific capacitances when compared with conventional electrostatic capacitors and therefore superior energy densities compared to electrostatic capacitors [29, 30].
