Dear researchers,
While performing Electrochemical Impedance Spectroscopy (EIS) in a supercapacitor with a two-electrode configuration (e.g., coin cell), why should the measurement be conducted at an OCV of 0 V*?
* Please consider the following:
- 1 M H2SO4 electrolyte;
- working voltage window between 0 V and 0.8 V;
- NTP conditions.
All the best.
Ioannis Samaras
The (initial) Vdc parameter for the EIS measurements is (Vdc =) 0V in (nearly all) symmetric, same (carbon based, two-) electrodes, coin cell, supercapacitors, since it is a counterbalanced cell, near to equilibrium, idc= 0 A (at Vdc= 0 V) .
