Wet Tantalum Electrolytic Capacitor technology is well-established. It uses a tantalum pellet inserted into a can, also usually fabricated in tantalum for best performance, which contains an electrolyte solution. Cathode systems with high capacitance are created on the internal surface of the can or as a tantalum sleeve insert.
Tantalum and Tantalum Polymer (TaPoly) capacitors are also high CV devices, but extremely stable across temperature and voltage. Electrochemical Double Layer Capacitors (EDLC), commonly known as supercapacitors, are peerless when it comes to bulk capacitance value, easily achieving 3000F in a single element discrete capacitor.
These capacitors, similar to other electrolytic types, consist of an anode, electrolyte, and cathode. The cathode can be either solid or liquid, but currently, the majority of tantalum electrolytic capacitors available on the market are of the solid variety.
Unlike EDLC or batteries, the stable construction of wet tantalum capacitors with a solid Ta2O5 dielectric enables higher frequency AC operation with DC BIAS (depending on construction) and therefore these devices are suitable for use in power supplies as bulk smoothing capacitors. Figure 1.
The first samples of DC Wet tantalum capacitors using the principles described in the previous chapter were prepared achieving a high DC capacitance of 50mF at 6.3V rated voltage in a T4 standard wet tantalum case size.
It is also interesting to note that conventional 75V wet tantalum capacitors have a similar energy volumetric density to the low voltage aqueous super-capacitors, as the energy is a function of voltage squared. Fig.9. DC capacitor benchmarking table
Standard specifications for wet tantalum capacitors define the capacitance reference value at a frequency of 120Hz. This is starting to become a limiting factor for the use of next generation higher CV powders as capacitance at 120Hz may be low - see Fig.8. Fig.7.

Overview of Supercapacitors. One alternative to the chemical battery for storing electrical energy is the supercapacitor. Also known as the Electric Double-Layer Capacitor (EDLC), supercapacitors are built from electrodes coated in a porous material, which is usually carbon-based, separated by an electrolyte that is itself divided by a membrane.

Supercapacitors provide longer-term processing power. Once the charge depletes from the supercapacitor, the Tantalum start-up capacitor provides voltage and powers the MCU in a maintenance state until the supercapacitor becomes fully charged and processing functionality returns to a high level.
In 1975, studies by Conway on underpotential deposition of H on Pt or oxidation/reduction of RuO 2 led to the term "supercapacitor" (SC) [2]. Because electrochemical reactions occur in supercapacitors, they are often confused with battery cells, in this article we want to clarify where the key differences and similarities lie between the two.
