Production technology – SUPERCAPACITOR

Objective

Battery type supercapacitor of the new generation

SUPERCAPACITOR/

Stage:/

Concept/

SUPERCAPACITOR (SC) is a capacitor without the usual insulation between the capacitor plates: instead of the conventional insulating dielectric is used double electric layer (DEL), in which charge accumulates at the interface of two media – electrode and the electrolyte.

There are several basic designs of supercapacitors, but most of the electrodes are made of porous carbon. Between the electrodes located separator – dielectric, separating two electrodes and permeable to electrolyte ions. When voltage is applied to electrodes – DEL will be formed. Functionally it is a hybrid of capacitor and chemical cell – the electrochemical capacitor.

Concept/

  • Highest specific capacity out of all kinds accumulators (both volumetric and weight)
  • Durability – more than 10 years and 100.000 charge / discharge cycles
  • Very fast processes of battery charging – up to 100% of capacity from 15 to 40 minutes (depending mainly on the capabilities of the charger)
  • Possibility of obtaining a large inrush current
  • No need to maintain – SC is sealed
  • Relatively low rate of self-discharge – up to 10% per month
  • Environmentally friendly (SC is based on coal)

Quality of the supercapacitor is determined by:

  • Bond strength of the electrode with the collector
  • Junction resistance of foil-carbon layer and size of the electrode capacity (f / cm² * nm)
  • Thermal stability of the separator

Our technology greatly improves all of these three basic components of modern supercapacitor: collector, electrode, and separator. In fact, we have made the breakthrough, allowing quickly charge and discharge the supercapacitor, but at the same time:

  • Reliability and durability of products have increased significantly (through the improvement of the collector)
  • Much more energy is accumulated. It allows to reduce the weight and size of the supercapacitor (through the improvement of an active electrode)
  • Supercapacitor became more heat resistant and safe (through the improvement of the separator)
  • Moreover, all three elements are used not only in the production of supercapacitors but may be sold separately, very quickly taking a leading position in the market in regard of price and quality
  • Strictly speaking, we offer not one but three technologies by means of which it is already possible to assemble the fourth – storage condenser
  • All three technologies are manufactured with the use of costs efficient magnetron coating technology
