Theory of Ragone plots

The general theory of Ragone plots for energy storage devices (ESD) is discussed. Ragone plots provide the available energy of an ESD for constant active power request. The qualitative form of Ragone plots strongly depends on the type of storage (battery, capacitor, SMES, flywheel, etc.).For example, the energy decreases as a function of power for

Ragone Relations for Thermal Energy Storage

This power and energy nexus is equally relevant for thermal energy storage materials for thermal management applications that require a balance between energy storage capacity and on-demand cooling or heating rates. Here,

Optimizing energy storage devices using Ragone plots

Ragone plots have so far been mainly used for a rough comparison of energy storage technologies across orders of magnitude in either power or energy capability. However, with suf®cient care in the de®nition and suf®cient accuracy in the measurement of Ragone plots, they may serve as a realistic conceptual tool for the actual design of energy

Ragone plots revisited | Research@Leibniz University

The term "Ragone plot" refers to a popular and helpful comparison framework that quantifies the energy–power relationship of an energy storage material, device, or system. While there is consensus on the general Ragone plot concept, many implementations are found in the literature.

Theory of Ragone plots

Since the efficiency of an ESD is usually dependent on the working point, a single device belongs to a whole curve in the energy–power plane (see inset of Fig. 1).These so-called Ragone plots, which are usually presented in a log–log plot, are standard in the battery community since a long time [1] rst, they provide the limit in the available power of a battery
