Abstract
The arrangement for supercapacitor device comprises an electrode (1) provided with an electrically conductive element (4). It also comprises a separator element (3) fixed against a first face (4a) of the electrically conductive element (4), the arrangement being perforated with a plurality of through holes (5) which pass through both the electrically conductive element (4) and the separator element (3). The perforated separator element (3) forms a membrane that is both electrically insulating and porous to ions of an electrolyte of the supercapacitor device. The electrically conductive element (4) of the electrode (1) being perforated, the equivalent surface area of the electrodes of the supercapacitor device is dependent on the number of holes made and on their depth.
