Ragone plot
Ragone plot showing specific energy versus specific power for various energy-storing devices. A Ragone plot (/ r ə ˈ ɡ oʊ n iː / rə-GOH-nee) [1] is a plot used for comparing the energy density of various energy-storing devices. On such a chart the values of specific energy (in W·h/kg) are plotted versus specific power (in W/kg). Both axes are logarithmic, which allows comparing
