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.
