Supercapacitors — what is it

technology1
Supercapacitor (ionistor) — promising storage energy and current source. According to its technical characteristics , it occupies an intermediate the position between rechargeable batteries and traditional capacitors. In a supercapacitor, the charge accumulates due to the formation of a double electric layer on the surface of the electrode as a result of the adsorption of ions from electrolytes.
technology2
The principle of operation — in the case of applying a potential difference to current leads, negative ions are formed at the cathode, and positive ions are formed at the anode from the electrolyte. The dielectric porous separator passes electrolyte ions and does not allows short circuits between the electrodes.
The principle of energy storage— electricity is saved statically, due to the polarization of charged electrolyte particles, while in the process there are no electrochemical reactions of charge-discharge.

Service life
Another important advantage is a huge resource. Lithium-ion and lithium-polymer batteries have a decrease in capacity relative to the original values are observed after several hundred charge-discharge cycles. And supercapacitors they can withstand up to one million cycles without noticeable degradation.
Application
Ionistors are used as a power source in ground-based transport. Also in consumer electronics, when you need to charge your device quickly. For example, in players, flashlights, flashlights, counters, laser cancer detectors, in launchers internal combustion engine devices, etc.
CELL CHARACTERISTICS
technology4
Thanks to the original design, the base cells of the modules supercapacitors have a number of advantages:
  • Minimum number of parts in a cell
  • Minimum internal resistance
  • Switching occurs along the entire side surface of the cell
  • Maintaining operability after short-circuit current tests
  • Optimization of current and thermal fields
  • Reduction of the mass of the cell and the assembled module
