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.

Storing thermal energy collects cold or warmth in water, rock and chemical solutions during one time for use during another. A simple example is heating steel drums of water in the sun during the day to collect heat, and then relying on that heat during the cold of the night as it dissipates. Stored heat and cold can be used hours, days, even ...
