The fastest growing technology is the lithium-Ion market, which is largely driven by the electric vehicle (EV) market. In recent years, the use of BPS-connected battery energy storage has quadrupled from 214 MW (2014) to 899 MW (2019), and NERC anticipates that the capacity could exceed 3,500 MW by 2023 (Figure I.3).
Energy consumption in the world has increased significantly over the past 20 years. In 2008, worldwide energy consumption was reported as 142,270 TWh [1], in contrast to 54,282 TWh in 1973; [2] this represents an increase of 262%. The surge in demand could be attributed to the growth of population and industrialization over the years.

Electrochemical Energy Storage. Electrical energy storage and sector coupling technologies are the key to a successful energy transition. Fraunhofer UMSICHT develops electrochemical energy storage for the demand-oriented provision of electricity as well as concepts to couple the energy and production sectors.
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.
