My solid polymer electrolyte shows low bulk resistance show quite a low bulk resistance. However, the potential window (obtained from LVS) is very small. Please how can I improve the operating potential window?
The potential window boundaries are determined by the chemical equilibria of the substance. So for a given substance it is impossible to move these.
Dear Abdullahi Abbas Adam,
how low[1] (or, better, what) is the 'measured' window (potentials' limits vs. which RE ?) ?
Also, say, if possible, what are (a l l) the (other) materials' parts of your cell ?
1. As Vadim S. Gorshkov say "theoretically, it is impossible to increase...", but, in practice, you might do the opposite, e.g. you might 'rob' (disserve) any of the actual potential window (V-low, or V-high) boundaries, by selecting unfavorable (or even troubling) electrode materials (or even some harmful metallic substrate(s)) for this (gel? or solid?) electrolyte case.
I did not optimize yet. As you said, "It may affect the potential window but not so much". I was expecting a little potential window which can be improved after optimization. On the contrary, the curve no sign of stability An Giang Nguyen

I did not get the information please.
The cell comprised of the solid electrolyte, activated carbon electrode and nickel foam current collector.
Dear Abdullahi Abbas Adam,
could you show, please, some LVS (or CV) plots, that are related with the (low) potential window. for this cell (solid electrolyte ?) ?
I didn't save the plots because I felt the results were not good enough Ioannis Samaras
ok, dear Abdullahi Abbas Adam.
Whenever you repeat it, and find yourself ready, then, maybe, you can show/send some plots, for more comments.
