Li-ion batteries will be the energy storage system of choice for both small -and large scale applications in the foreseeable future. While the technology has been around since 1991, there is still a lot of improvement to be made before the systems reach their full potential. Today, most improvement is found at the interface between the electrolyte and the electrode. In Imec, these interfaces are studied using thin-film model systems. These Thin-film batteries (1) can be integrated into 3D structures to create high power and high capacity microbatteries and (2) serve as a model system used to characterize interfaces in the battery. In this thesis, dual conductive materials are characterized using model systems. In a first phase, these materials will be deposited on top of inert current collector substrates to measure their electronic and ionic properties. In a second phase, they will be deposited on Li-ion battery electrodes to characterize the effect of these coatings on battery performance. Optionally, Finite element modeling can be done for analysis of Lithium dynamics in the dual conductive materials
