Ragone plots and discharge efficiency-power relations of
The normalized Ragone plot for the ideal battery as a function of the normalized power p = P / P max finally becomes (5) e (p) = 1 + 1 − p 2. where p / (1 − 1 − p) = (1 + 1 − p) was used. Because the battery is fully discharged at t = t ∞, the Ragone plot is equivalent to the discharge efficiency-power relation, η (p) = e (p).

Ragone plots and discharge efficiency-power relations of electric
The power-dependent normalized Ragone plots, e(p), and the discharge efficiencies, η(p), of ideal electric and thermal ES devices with either constant (battery, latent heat ES) or decaying (capacitor, sensible heat ES) intensive thermodynamic variables (electro-chemical potential, temperature) were derived and discussed for simple
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
