Customer Service1. Introduction Electrochemical capacitors (often called supercapacitors or ultracapacitors) are devices capable of storing electric energy in the electrical double–layer, which is formed at the electrode/electrolyte interface.
Based on the obtained results, it is concluded that the corrosion process of current collectors significantly influences the long–term performance of electrochemical capacitors. This influence appears much faster than the degradation of the electrode material and cannot be neglected once long–term performance is evaluated.
For capacitors, typically high leakage or short condition results from either dielectric compromise or bridging across the positive and negative terminals, what causes this and how it occurs varies for the different CAPS.

During the second series of tests, i.e., after 100 h of floating, the Q c value of the SC/12 electrochemical capacitor decreased. After 24 h of relaxation under open circuit conditions, it increased and from that point, it started to decrease again. The value of the Q dl remained at approximately the same level during the 200 h of floating.
