Abstract: 
Capacity loss mechanisms of lithium-ion batteries (LIBs) are intensively studied. In this study, planar LiCoO2 (LCO) thin film electrodes are successfully prepared by pulsed laser deposition and used to explore a diffusion-controlled reversible capacity loss mechanism of layered oxide cathodes. It is found that the reversible capacity loss of LCO originates from asymmetric lithium chemical diffusion kinetics during (de)lithiation, which is eventually rooted in the intrinsic lithium vacancy dependent diffusivity in the layered structure of LCO. The understanding of the reversible capacity loss may be highly beneficial for the development of LIBs and other systems based on intercalation compounds.
