Practical Aspects of Preparation and Evaluation of Electrochemical Capacitors

  • B. E. Conway


The key components in an electrochemical capacitor are the electrode, electrolyte, and the separator materials. Most electrochemical capacitors, except the hybrid type,1 are made with identical electrodes, i.e., preparation of only one type of electrode is necessary, unlike in batteries. However, as the specific capacitance (e.g., of a carbon electrode) when positively polarized is usually different from that of the same material when it is negatively polarized, some allowance for this can be made by using a different quantity (weight or volume) of the active material in the two electrodes. Then the resulting device should be polarity labelled.
