Abstract From the Canadian patent

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 …
