CAPACITOR WITH A DOUBLE ELECTRICAL LAYER

摘要

The invention is essentially a capacitor with a double electrical layer and comprising a housing (1), collecting metal plates (2) secured under pressure within the said housing, polarizable carbon electrodes (3), and separators (4) permeated by an aqueous electrolyte. The collecting plates (2) are of metal with a surface microhardness lower than the hardness of the material of the polarizable electrodes (3).
