Dear RG colleges,
Is it possible to calculate energy and power of a single electrode from constant current discharge. For the whole battery or pseudocapacitors it is relatively easy, integrating the voltage (nonlinear) over time curve and multiplying by current. Dividing by time, power could be obtained. In the case of single electrode, for example lead-lead sulfate discharge occurred nonlinear in the potential range -0.5 to -0.65 V (SCE). So, does the energy corresponds only to the integral in that potential range during discharge time, and does that have any seance.
Dear Prof Branimir N. Grgur,

I believe that energy and power densities of single electrodes are of no physical meaning. The two terms are reserved for devices. Although there are some papers reporting the energy and power densities of single electrodes, I respectfully disagree with them.

Dear Branimir N. Grgur Sir,
The energy and power densities for a device for example; a battery or a supercapacitor can be calculated. Single electrode is providing only the materials performance but the calculation of energy and power density value from the discharge curve is having no significance.
Thank you.
