Supercap cells

Unlike batteries, ultracap cells can withstand one million charge/dis­charge cycles and can absorb and release very large amounts of energy at lightning speed. Ultracaps are also lighter than batteries and can be dis­posed of or recycled in a more environ­men­tally friendly manner.

Performance + lifetime = sustainability

Since its market intro­duction at the beginning of this century, this techno­logy has opened up many areas of appli­cation.
The advantages speak for them­selves.

  • Fast storage of high power
  • Low internal resistance - Fast output of high power
  • High cycle stability
  • Good temperature properties, especially at low temperatures
  • Long life (longevity)

Battery vs Supercap

Compared to rechargeable batteries, supercapacitors are unbeatable in absorbing and delivering high power. However, it depends on the specific requirements.

Why are components like ultracaps called different names?

The variety of terms is explained by the English-language terms commonly used in the electronics industry, which are often mixed with German terms or used synonymously. In some cases, manufacturers have also introduced artificial terms to better distinguish themselves from competitors. Here are the most important examples:

Double layer capacitors (DSK) are referred to synonymously as:

  • EDLC (Electric Double Layer Capacitor)
  • Supercapacitors = Supercaps
  • Ultracapacitors = Ultracaps
  • Goldcap™ [Panasonic]
  • Boostcap™  [Maxwell]
  • Greencap™  [Samwha]
  • PURIXEL™  [Pureechem] for supercap cells
  • PURETRON™  [Pureechem] for supercap modules
