Electrochemical storage and energy converters are categorized by several criteria. Depending on the operating temperature, they are categorized as low-temperature and high-temperature systems. With high-temperature systems, the electrode components or electrolyte are functional only above a certain temperature.
Abstract. 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
