ASYMMETRIC ELECTROCHEMICAL CAPACITOR

摘要

The present invention pertains to electric capacitors having a large capacity and used for accumulating electric energy, and essentially relates to asymmetric electrochemical capacitors. The asymmetric electrochemical capacitor of the present invention has a substantially increased specific energy as well as an extended service life. To this end, the asymmetric electrochemical capacitor comprises a body (5), at least one installed pair of electrodes comprising a first (1) and a second (2) electrode, an electrolyte (3) arranged between said electrodes, a collector and a separator (4). The absolute capacities of the electrodes are different, i.e. the first electrode has a higher absolute capacity than the second one. One of the electrodes is made of a material allowing for the energy build-up during a Faraday process, while the other electrode is made of a material allowing for the energy build-up in a dual electric layer.
