The development of Flexible Organic Battery Technology applied in Organic Light Emitting Diode (OLED), using an flexible optically transparent substrate material and organic semiconductor materials, has been widely utilized by the electronic industry when producing new technological products. The Organic Battery are the base Polyaniline, PANI, Lithium Perchlorate, LiClO4, and Polymethylmethacrylate, PMMA, were deposited in Indium Tin Oxide, ITO, and characterized by UV-Visible Spectroscopy (UV-Vis), Electrical Parameters (EP) and Scanning Electron Microscopy (SEM). In addition, the thin film obtained by the deposition of PANI, prepared in perchloric acid solution, was identified through PANI-X1. The result obtained by UV-Vis has demonstrated that the PVDC/ITO/PANI-X1 layer does not have displacement of absorption for wavelengths greaters after spin-coating and electrodeposition. Also, both electrodes have been united by an electrolyte solution prepared with Lithium Perchlorate, LiClO4, and Polymethylmethacrylate, PMMA. Thus, the result obtained through electrical measurements has demonstrated that the flexible organic battery presented the characteristic curve of standard battery after spin-coating and electrodeposition. Accordingly, the results obtained with optical and electrical characterization have revealed that the flexible organic battery demonstrated some change in optical absorption, when subjected to a many of charge and electric discharge. Moreover, the inclusion of the PANI-X1 layer reduced the effects of degradation that this charge and electric discharge caused. Studies on Scanning Electron Microscopy (SEM) have found out that the surface of PANI-X1 layers can be strongly conditioned by the surface morphology of the dielectric.
