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

Failure limit analysis for Li-ion batteries using Ragone plot: a

Abstract: In this paper, a new possible definition of failure zone for Li-ion batteries is proposed. Based on the general concept that a battery can be considered failed when its performance no longer meets the requirements of the application for which it is designed, a new application-dependent failure zone definition is proposed using the Ragone plot of the cell.
