Crystal alignment of graphite as a negative electrode material of the lithium-ion secondary batteries

The major problem on magnetic alignment of graphite particles is the difficulty to produce graphite particles composed of a single crystal, and suppress their agglomeration. Thus, it is essential to produce graphite particles composed of a single crystal and disperse them using mechanical grinding or shearing with addition of a suitable dispersant. In this study, the suitable dispersant for graphite particle and the optimum condition for mechanical grinding are studied in respect to the crystal alignment of natural graphite in slip casting under a high magnetic field.
