Abstract
Effect of the phase-boundary potential at the electrode-electrolyte interface and the anisotropy of interfacial energy on the morphology of the electrodeposits have been investigated by phase-field simulation. In equilibrium system, the change in the phase-boundary potential due to the interfacial curvature satisfies the Gibbs-Thomson effect. The stability analysis of the electrode-electrolyte interface reveals that the marginal wavelength is proportional to the inverse of the square root of the growth velocity of the interface. It is found that the linear relationship between the marginal wavelength and tip radius during electrodeposition satisfies the crystal growth theory confirmed by the dendrite growth in solidification process.
