Abstract

To improve the energy density and practical realization of the all-solid-state Li-ion secondary battery, the principal requirement is a high electric conductivity in the densely sintered positive electrode. To accomplish this task, we focused on the anisotropic Li-ion and electron conductivities of the LiCoO2. As a result of our work, the ideal design of the texturing, perpendicular alignment of the c-plane and horizontal but random orientation of the c-axis on the electrode, was proposed. The battery performance of the ideal textured cell fabricated using a rotating strong magnetic field has a significantly higher performance than a randomly oriented cell.
