Abstract

We demonstrate the deposition of LiCoO₂(11-20) epitaxial thin films on chemically etched Pt(110) substrates, and compare their electrochemical properties with those of LiCoO₂(10-14) epitaxial thin films on sputter-annealed Pt(110) reconstructed substrates. Cyclic voltammogram measurements of LiCoO₂(11-20) epitaxial films exhibit stable charge and discharge operations, despite the application of a compressive strain on the films.
