摘 要：In this paper,the spherical particles growth during lithium electrodeposition was investigated by directly solving the governing equations based on the Landau transformation *** basic growth kinetic characteristics of a spherical particle during electrodeposition was *** results show that the dynamic oscillation of the growth velocity occurs during the spherical particle *** was found from numerical simulations that applied electrical potential difference,electrolyte concentration,and diffusion coefficient are 3 main factors influencing the spherical growth and the existence of the dynamic oscillation state of the growth velocity during *** increase in both the applied electrical potential difference and the electrolyte concentration can lead to the increase of the growth velocity of the spherical particle,while the growth velocity is independent of the diffusion ***,it was found that the wavelength and the amplitude of the dynamic oscillation of the growth velocity can be influenced by the applied electrical potential difference,the electrolyte concentration,and the diffusion *** determined that the dynamic competition between electrochemical reactions and ion transport in the electrodeposition is the reason for the existence of the oscillation of the growth velocity.
