Abstract

We demonstrate the orientation control of LiCoO₂ epitaxial thin films deposited on (110)-2 × 1 reconstructed surfaces of Au and Pt by using pulsed laser deposition. The epitaxial LiCoO₂ thin films have CoO₂ layers tilted with respect to the surface normal, which is suitable for Li-ion insertion/extraction reactions in LiCoO₂. We show the successful operation of all-solid-state thin-film Li-ion batteries by employing the epitaxial LiCoO₂ thin films as cathodes. The electrochemical properties of epitaxial films in all-solid-state batteries are improved compared to the batteries using liquid electrolyte.
