Two electrodes that are segregated make up the basic supercapacitor design. A separator, a type of semi-permeable membrane, is used to protect against electrical contact between electrodes . The membrane is slightly porous to allow for high ionic conductivity and ionic charge transport with low thickness, high electrical impediment, and conductivity combining to produce the best results. The separator and electrodes are then submerged in an electrolytic solution, that is by allowing the flow of current between electrodes, you can stop cells from discharging. This permits the electronic current from flowing across the electrodes by allowing the flow of ionic current instead. removing the cells' charge .
