Abstract :
Thin film bilayers of LiNbO3/C have been formed on substrates of stainless steel/TiN and Al2O3/Co/Pt. These samples have been treated thermally and measured with an AC impedance analyzer in order to evaluate their ionic behavior. Subsequently, solid state microbatteries, using LiCoO2as cathode material, have been prepared on the same substrates. Both the LiCoO2/LiNbO3/C and the inverse structure have been fabricated. AC impedance spectroscopy reveals that deposition of the electrolyte on the cathode layer is more active, while the substrate of the whole structure influences significantly the ionic resistivity of the electrolyte.
