The analysis of the grain growth of the oriented LiCoO₂ prepared by colloidal processing using a strong magnetic field

Abstract

LiCoO₂, which has layered rock-salt structure, is used as positive electrode material for Li-ion batteries. In this study we attempt to produce crystalline-oriented LiCoO₂ by slip casting in a strong magnetic field. And we analyzed the relationship between the grain growth and the crystal orientation. As a result, it was revealed that the grain growth was suppressed by the crystal orientation.
