Abstract

LiCoO₂ is a popular positive electrode material for Li-ion secondary batteries. The perpendicular alignment of the interlayer of the LiCoO₂ lattice on the electrode contributes to easy access of Li-ions. In this study, we report the preparation of an oriented LiCoO ₂ sheet using the conventional coating method followed by drying in a maximum 12T strong magnetic field. We discuss the effect of the particle shape and viscosity of the paste on the degree of orientation. As a result, when the sheets are dried in a strong horizontal magnetic field, the electrochemical active planes of the LiCoO₂ are aligned perpendicular to the sheet surface.
