In this paper, LiCoO2 thin films deposited onto the silver (Ag) coated glass (Ag/glass) substrate and then LiCoO2/Ag/glass half-cells were test in full cell test procedure. X-ray diffractometer (XRD) analysis, surface imaging with a field emission scanning electron microscopy (FESEM), optical properties were used for the determination of the microstructural, surface and optical properties of the deposited thin films. The cyclic voltammetry (CV) and capacity measurement were done using a full cell test procedure in liquid ionic electrolyte. Pt or ITO coated glass were used as an opposite electrode in electrochemical test. According to the XRD measurements, some reflections corresponding to the LiCoO2 and Ag layer (cathode current collector) were detected. All electrochemical tests were done in the 0.1 M LiClO4 in propylene carbonate. The anodic oxidation and cathodic reduction were observed in CV experiments. Especially, oxidation and reduction peaks were clear in the experiment of the ITO coated electrode. (C) 2018 Elsevier Ltd. All rights reserved.
