Specific power versus energy, Ragone

A Ragone Plot compares the performances of different energy storing devices by plotting power densities or specific power [W/kg] versus energy densities or specific energy [Wh/kg]. Electromobility is a mobility concept in which electric vehicles instead of vehicles powered by internal combustion engines are used.
