A parametric study has been carried out on the exchange current density, in order to emphasize the effect of double layer capacitance on cell voltage response. It can be noticed here that the values used for the exchange current density in Smith and Wang''s work [3] are large, around one order of magnitude [16], or even more [17], higher than that used in some
When that battery is suddenly connected to a load, the capacitive effect allows a sudden and brief surge or "transient* of current to flow out of the battery which the electrochemistry of the battery itself couldn''t ordinarily provide. This is the sort of thing that "peaking behavior" refers to.
lower and the state of the charges of the battery had a little effect on it. However, at high temperatures, the values of the double layer capacitance were much higher and it increased by 900% when the temperature was changed from -20 ºC to 50 ºC at the 50% SOC condition.

• A capacitor is a device that stores electric charge and potential energy. The capacitance C of a capacitor is the ratio of the charge stored on the capacitor plates to the the potential difference between them: (parallel) This is equal to the amount of energy stored in the capacitor. The E surface. 0 is the electric field without dielectric.
