Specific energy vs. specific power or Ragone plots, Maybe you can find some information fromt this report.

Hope you have done the specific capacitance calculated from the charge/discharge test. Take the discharge timings from this into a column. From the specific capacitance and the potential window, you can calculate energy density by using the formula E = 0.5 CV^2 (make sure of units, the sample mass you might have used as gram, so don't forget to convert them to kg. Since, energy density will be in Wh/kg). Divide the energy density by time (convert Sec into hour) in order to get power density in W/kg. Plot energy density vs power density ( you will also have option to plot them in 3D including varies charge/discharge current density along the third axis).
Dear Mohit,
Ragone plot relates the energ and power density of a energy storage device. Since you want to plot it in origin, you can do the following steps...

Are you talking about the plot??? You can calculate energy and power density for various current densities and plot them in 3D plot...(keeping the current density in 3rd axis)
