我们证明了树枝状镁沉积物的生长与分形形态表现出剪切模量超过值的聚合物隔板后，恒电流电沉积金属镁从格氏试剂在对称的Mg-Mg细胞。枝晶生长的基础上理解的反应速率，电解质传输速率，和自扩散障碍的竞争影响。
We demonstrate the growth of dendritic magnesium deposits with fractal morphologies exhibiting shear moduli in excess of values for polymeric separators upon the galvanostatic electrodeposition of metallic Mg from Grignard reagents in symmetric Mg-Mg cells. Dendritic growth is understood on the basis of the competing influences of reaction rate, electrolyte transport rate, and self-diffusion barrier.
