Ultracapacitor, also known as supercapacitor, supercondenser, electric double layer capacitor (EDLC) or pseudocapacitor, is an electric capacitor that has an unusually high energy density when compared to common capacitors, typically on the order of thousands of times greater than a high capacity electrolytic capacitor.
Nesscap’s small-sized EDLC cells range from 3F to 50F in capacitance with operating voltages ranging from 2.3V to 2.7V. These cells can be used in various types of applications which mainly require smaller amounts of capacitance but immediate pulse power, such as, AMR (Automatic Meter Reading), consumer electronics and SSDs (Solid State Drives)
Nesscap offers multi-cell modules with operating voltages of 5V, 16V, 48V, 64V, 86V, and 125V, to satisfy higher voltage requirements of many integrated systems. These standardized multi-cell modules can simply be connected in series to meet even higher voltage requirement. 5V modules (composed of two 2.7V 3F cells connected in series) are typically used for AMR and other applications which require small amount of capacitance and mainly used for small pulse power. 16V and higher voltage modules are composed of large cylindrical cells target the automotive and industrial application such as transit bus and heavy duty vehicles.
Nesscap’s small and medium-sized Pseudocapacitor cells range from 50F to 300F in capacitance with operating voltage of 2.3V. This proprietary technology is one of the first commercially available hybrid capacitor products on the market. A Pseudocapacitor will store approximately twice the energy of a typical EDLC of the same size and weight with lower cost per unit of energy. There is a growing and significant opportunity for Pseudocapacitors especially in portable and handheld products.
