Ragone Plots

Ragone plots are graphical representations used to compare the energy density and power density of various energy storage systems. These plots help visualize the trade-off between how much energy a device can store (energy density) and how quickly it can deliver that energy (power density), which is crucial for understanding the performance of different technologies.

Ragone Relations for Thermal Energy Storage Technologies

Introduction. A half century ago, Ragone published an overview of electro-chemical and fuel-cell batteries (Ragone, 1968) to compare power and energy performance of batteries in electrical automotive applications, prior to the emergence of plug-in electric vehicle (EVs) (Rotering and Ilic, 2011).This graphical comparison, later termed a "Ragone plot," visibly and quantitatively
