The liquid metal pad and cell voltage oscillation, and the Fourier power spectra of
the non-linear cell stability analysis results are presented in Figure 16. At 20 cm of metal
pad thickness, the results indicate that at best, the cell will only be marginally stable due
to the intensity of the lateral (Jy) current density field. Figure 17 presents the obtained
bath-metal interface wave pattern.

10 CM METAL PAD CASE

Figure 18 shows the metal pad current density field when the metal pad thickness
is reduced to only 10 cm. The resulting metal pad and cell voltage oscillation, and the
Fourier power spectra of the non-linear cell stability analysis results are presented in
Figure 19. As we can see, at 10 cm of metal pad thickness, the horizontal current
intensity doubled and as a result, the cell is predicted to be completely unstable.
