This capacitance loss in the millisecond region is caused by the charge transfer (i.e. establishment of
capacitance) being carried out primarily by relatively slow moving ions in double layer capacitors. In the
above-mentioned “electronic” capacitors, the charge transfer is performed by fast electrons, thereby creating
virtually instant rated capacitance value. Fig. 2 illustrates the severe capacitance loss experienced by several
varieties of supercapacitors (N, M & P), under short pulse width conditions. It can also be seen from Fig. 2,
