Abstract: The energy content of supercapacitor is determined by its capacitance value and working voltage. To attain a high capacitance and a high voltage, several pieces of electrodes and separators are spirally wound with edge sealing to form a bipolar supercapacitor in cylindrical, oval or square configuration. While the winding operation effectively provides a large surface area for high capacitance, the bipolar packaging instantly imparts a unitary roll a minimum working voltage of 5V on using an organic electrolyte. The bipolar roll is a powerful building block for facilitating the assembly of supercapacitor modules. Using containers with multiple compartments, as many bipolar rolls can be connected in series, in parallel or in a combination of the two connections to fabricate integrated supercapacitors with high energy density as required by applications.
