Fig. 5: Schematic illustration of Al passivation and corrosion.
From: Passivation and corrosion of Al current collectors in lithium-ion batteries

Chronoamperometry results measured at various applied potentials, a the whole i-t curves for pristine Al||Li at 4, 4.2, 4.3, 4.4, 4.6, 4.8, and 5.0 V. The current collectors were cycled 3 times with a scanning rate of 10 mV s−1. SEM and AFM images for Al foils at (b, c, h) 4.2 V, (d, e, i) 4.4 V, and (f, g, j) 4.8 V.
