Li+ diffusion in solid phase during the charging-discharging process of battery materials , is the control step. The morphology and  size of the crystal to some extent determines the length of the diffusion path, and therefore significantly influences the Li+ diffusion.

In the course of battery filling or discharging, the controlled step is the diffusion of Li+ in solid phase, and the distance of the diffusion of Li+ is determined by the shape and size of the crystal, thus the crystal shape affects the diffusion of Li+ dramatically¡£

During the process of  charging or discharging of battery, the controlled step is the diffusion of   Li-ion in solid phase, and the diffusion path of   Li-ion is determined by the morphology  and size of the crystal to a certain extent, so the crystal morphology  and size plays an important role in the diffusion of   Li-ion.
