As noted, depending on the requirements, different storage durations, maximum power ratings, and thus amounts of energy supplied are needed.

• Traditionally, the various storage methods are presented using a so-called “Ragone diagram” (Figure 4 ), that is, a double-logarithmic plot with specific power in W/kg or power density in W/dm ³ on the x-axis and specific energy in Wh/kg or energy density in Wh/dm ³ on the y-axis. Different storage media are represented by clouds, since the specific power and specific energy often vary depending on the system’s specific...
