  • the article reveals as one of the significant examples the measured data of capacitor batteries by many major manufacturers (Maxwell, NessCap, Power System, Asahi, Epcos), which confirm that specific energy values from capacitor batteries decrease 50-77% when compared with initial level per weight and 36- 70% per volume, depending on the capacitor connection diagram and dimensions. This factor is called packing density [A.F. Burke. Supercapacitor Technology - Present and Future. Advanced Capacitor World Summit 2006. San Diego, CA. July 17-19].
  • the manufacturers of super capacitor cells with best weight average and volume average specific parameters include Power Systems Inc. that uses housings made of lightweight materials (laminated aluminium and plastics) in manufacturing its capacitors. Using lightweight housings will guarantee higher weight and volume specific parameters for an individual cell, however when putting it into practice, the entire system still needs to be encased in the capacitor battery with an additional housing of reasonable material, which in turn will increase the weight and volume of the apparatus ([http://www.powersystems.co.jp ). For example, the packing density of a 59-volt capacitor battery, packed in this manner by so-called L4-cells in series connection, is 0.642 and 0.413, respectively, either per mass or volume [A. Burke, San Diego 2006].

Abstract

L'invention concerne un supercondensateur électrique à double couche qui présente une tension de fonctionnement élevée et des caractéristiques spéciales, et dont la conception comprend au moins deux cellules (2) électrochimiques connectées en série, placées dans un corps extérieur (1) ; les cellules voisines comportent entre elles une borne de courant commune, qui, par rapport à un élément, forme une borne négative, et par rapport à un autre élément forme une borne positive. Les cellules électrochimiques sont séparées l'une de l'autre par un blindage métallique (7), la tension de fonctionnement maximum du supercondensateur étant approximativement égale à la somme de la tension de fonctionnement maximum appliquée aux composants de la cellule électrochimique dudit supercondensateur.
