Electrochemical capacitors. ECs, which are also called supercapacitors, are of two kinds, based on their various mechanisms of energy storage, that is, EDLCs and pseudocapacitors. EDLCs initially store charges in double electrical layers formed near the electrode/electrolyte interfaces, as shown in Fig. 2.1.
However, the energy storage material is dissolved in the electrolyte as a liquid and so can be stored in external tanks. Various types of flow batteries are available or under development. Three of the more important examples are discussed in some detail: the all-vanadium flow battery, the zinc–bromine hybrid flow battery and the all-iron slurry flow …
