Fig. 3: Morphological evolution of the Li metal depositions.
From: Effect of the supergravity on the formation and cycle life of non-aqueous lithium metal batteries

Schematic illustrations of the nucleation and growth of Li metal under a, d 1G gravity, b, e perpendicular and c, f parallel supergravity conditions. Note that “E” represents the applied electric field, “F” represents the applied supergravity, and the color change represents the difference in ion concentration in the solution.
