Herein, we probed the above behavior by chronopotentiometry, characterizing the potential change upon application of negative/positive currents and investigated the effects of current density on the redox reactions of solvated lithium ions.
Chronopotentiometry was carried out in a 1.0 mol [L.sup.-1] solution of ethanol in SE at a constant current density of 3 mA [cm.sup.-2] for 15 h to evaluate the effects of CO poisoning.
Current densities of 3.0 mA [cm.sup.-2] were applied for 15 hours at chronopotentiometry experimental (CP).
Morphologies and microstructures of the samples were investigated by field-emission scanning electron microscopy (SEM) and transmission electron microscopy (TEM), while cyclic voltammetry (CV), chronopotentiometry (CP), and AC impedance were carried out to study capacitive properties of the films.
