Basically, The open circuit potential of any electrode is independent of its area as it is an extensive property . Therefore, the thickness of the electrode disk will not affect the Open Circuit Voltage of a Battery. The unit is always in Volt.
Hi there,
I agree with Dr.Fakiha, but, the open circuit potential with long time stable as is indicator to form a thin film on the surface, so, I will say if you take 1cm2 and compared with 5cm2 is the time and /or film form in the same way ? I advise to achieve more experiments. Kindly, see attached file.
Regards,
may affect stability of the device. But output voltage value will depend on the junction you made.
Upon reaching equilibrium after cell fabrication, the OCV will stabilize
@Amruth, thicker electrodes will consume more electrolyte than thinner ones right? What if it forms a SEI/passivation layer on electrode surface when the battery is in aging condition ( we do wait for sometime before connecting it to circuit right?). If the resistance of the battery increases that time what will happen to OCV?
@Satish Bolloju - You are absolutely right! OCV tends to fluctuate until the added electrolyte penetrates the electrode and the interfaces are formed. That's why I mentioned reaching equilibrium in the answer.
