Abstract

We attempted to fabricate the oriented bulk LiCoO 2 using slip casting in a strong magnetic field. The shrinkage of the oriented green compact was measured using a dilatometer. It was confirmed that the oriented green compact undergoes anisotropic shrinkage. The shrinkage in the c-plane direction of the oriented LiCoO 2 was greater than that in the c-axis direction. The degree of orientation in the bulk LiCoO 2 was analyzed using XRD and electron backscatter diffraction; the c-axis of LiCoO 2 was oriented parallel to the magnetic field. Moreover, the orientation parameter, r, was 0.234, indicating that 92% of the grains was aligned with a tilt angle less than 10° between the c-axis and the magnetic field direction. The texturing led LiCoO 2 to anisotropy in the electric conductivity between the c-plane and c-axis directions. It was concluded that the magneto-scientific technique is a powerful method to fabricate highly oriented bulk LiCoO 2 .
