Analysis of nucleation/growth dynamics is important to understand the molecular mechanism on the electrode surface. The electrocrystallization mechanism of Mg anode in aqueous electrolyte was comprehensively investigated which can help us understand the surface discharge mechanism of Mg anode and provide a new theoretical idea for the development of high performance magnesium ion battery. The influence of applied potential signals on normal growth constant and active site numbers was studied using - transient curves. The dimensionless processed transient curves confirmed that the initial nucleation/growth process of Mg electrode in aqueous solution followed the diffusion-controlled three-dimensional instantaneous nucleation model.
分析成核/生长动力学对于理解电极表面的分子机制很重要。对镁阳极在水性电解质中的电结晶机制进行了全面研究，这有助于我们理解镁阳极的表面放电机制，并为高性能镁离子电池的开发提供新的理论思路。利用 - 瞬态曲线研究了施加的电位信号对正常生长常数和活性位点数量的影响。无量纲处理后的瞬态曲线证实，镁电极在水溶液中的初始成核/生长过程遵循扩散控制的三维瞬时成核模型。
