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.

3 FAQs about [Guadeloupe ragone plot energy storage]

Can Ragone plots be used for thermal energy storage?

Recent publications in the field of thermal energy storage have adopted the Ragone plot framework to great effect, see , , , . The most extensive investigation in this regard is . Here, analogies between electrochemical and thermal energy storage are developed, and Ragone plots are first adapted for TES.

Why is the Ragone curve bounded by the efficiency of the thermodynamic cycle?

In general, the Ragone curve is bounded by the efficiency of the thermodynamic cycle and the available energy is reduced at higher powers due to imperfect heat exchange. Both characterizations are theoretical but are a solid basis for further practical analysis. For details, the reader is referred to the respective publications [28,31].

Why are Ragone plots different in lithium ion batteries?

Both highlight the different operating behavior and the resulting different Ragone plots for the charge and discharge direction. This effect is due to the well-known voltage hysteresis that occurs in lithium-ion batteries .
