Surface modification of spherical LiNi1/3Co1/3Mn1/3O2 with Al2O3 using heterogeneous nucleation process YANG Zhi(杨 志), LI Xin-hai(李新海), WANG Zhi-xing(王志兴), ZHU Yong-jun(朱勇军) School..., spherical LiNi1/3Co1/3Mn1/3O2 was coated with Al2O3 by using heterogeneous nucleation process, and the physical and electrochemical properties were studied. The SEM images show that there is a uniform......
or experimental means, due to the complexity of DRX process and the limitation of experimental measures[12-13]. At present, the backcalculated method is mainly used to evaluate the value of nucleation rate..., the intragranular nucleation and the heterogeneously distributed dislocation density, which influence the DRX process in practice. Here, they are not considered in the simulation in order to compare......

In this case, Stokes collision of the second phase can not be neglected. 2 FORMULATION OF MODEL 2.1 Nucleation Generally, the homogeneous nucleation......
: The electrocrystalliztion nucleation and growth process of Ni-Fe alloy was studied using cyclic voltammetry and chronoamperometry. The results show that, in the case of high deposition overpotential, the nucleation/growth process of Ni-Fe binary alloy is 3-D instantaneous, and the growth rate of the previously formed nuclei increases with overpotential. However, at low overpotential, no distinguished......

-deposition process was proposed in this paper, and the study was mainly focused on the nucleation mechanism and technological process, using FeSO4, NiSO4 and mixture of these solution systems. 2... at a low cost. 4 Conclusions 1) Iron’s electrodeposition plays a leading role in the Ni-Fe co-deposition process. The nucleation mechanism of Ni-Fe co-deposition accords with a progressive nucleation......
