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. (C) 2016 Elsevier B.V.
