The respective voltagram (I-V curve) of each situation is obtained, and the reaction is performed in the optimum I-V ranges.
The voltagram of the electrochemical cell with 2 mm of tungsten wire immersed in the solution is shown on Figure 3, while the results for 3 mm are shown on Figure 4.
The electropolishing reaction is better carried out in the plateau region of the voltagram [7], leading to smoother surfaces and uniform removal of material, and in the lowest-possible voltage [5], thus lending lower oxide formation rates.
Different fixed potentials were employed according to Ep,a obtained by voltagrams reported in Figure 3, and the same electrode was used under all the corresponding chronoamperometric experiment.
For both cyclic voltagrams, there are two pairs of reversible peaks, oxidation and reduction peaks, corresponding to [Li.sup.+] extraction and insertion, which reflect the typical [Mn.sup.3+]/[Mn.sup.4+] redox process of the spinel structure in the 4 V domain [26].
