Overview of Supercapacitors
Overview of Supercapacitors
Supercapacitors, also referred to as ultracapacitors, are energy storage devices with power and energy densities between those of a traditional capacitor and battery. Batteries store energy chemically, whereas supercapacitors store them electrostatically. Supercapacitors use electrolytes and configure various-sized cells into modules to meet the power, energy, and voltage requirements for a wide range of applications. Supercapacitors store energy using either ion adsorption (e.g. found in electrochemical double layer capacitors) or using fast surface redox reactions (e.g. found in pseudo-capacitors). These supercapacitors can potentially provide on the order of one hundred times or greater the capacity compared to standard electrolytic capacitors.
Advantages of Supercapacitors
Bioenno Power offers a complete line of supercapacitors. The main advantages of Bioenno Power supercapacitors include: (1) tremendously enhanced Farad level capacity within a compact space and volume compared to standard electrolytic capacitors; (2) low internal resistance; (3) excellent deep cycle discharge performance; (4) cycle life that exceeds 100,000 times; and (5) environmental-friendliness. Supercapacitors offer high energy and power densities, have excellent cycle life, and can also withstand harsh temperatures.
Applications for Supercapacitors
Supercapacitors have become increasingly attractive for a wide variety of applications including the following:
- Automotive: Hybrid Electric Vehicles (HEVs), Partial Hybrid Electric Vehicles (PHEVs), Electric Vehicles (EVs)
- Defense: Weapons, tactical vehicles, EM armor, military power
- Commercial/Industrial: UPS equipment, telecom equipment, automatic meter reading equipment, remote controllers
- Consumer: Electric tools, RC models/toys
- Solar/Renewable: Solar power systems, wind power generators
Various Supercapacitor Configurations Available
Bioenno Power offers various types of supercapacitors in many configurations including (a) coin cell type and (b) radial/cylindrical type. For coin cell type capacitors, 5.5V units are available with Vertical, Horizontal, and Center terminals. For radial/cylindrical type supercapacitors, 2.7V units are available with both leaded and snap-in terminals. The capacitance values range from 0.10F to 400F. See the table below that shows each particular configuration based on model, voltage, capacity, dimensions, and weight.

Continued Research and Development on Supercapacitors
Bioenno Power is currently developing a novel class of high-energy-density, high-power-density supercapacitors using nanostructured carbon and graphene materials. These materials provide high energy density, high power density, and extremely long service life. We are also conducting work on the development of hybrid energy storage systems that combine Li-ion batteries and supercapacitors.
