The overall objective of the Project is to build a functional 3D thin film micro battery with a solid electrolyte, which inherently represent an improvement on the current Li-ion batteries with liquid electrolytes (in terms of safety and battery performance). Additionally, new roepassingen and makes it possible concepts battery (electric vehicles, micro-systems on chip, ...). To this end, have to be developed electrolyte materials, both conformal coating processes, and solid. Two deliverables are defined on: - A flat thin film battery with a focus on the conductivity of the solid electrolyte. - A 3D thin-film battery with a focus on compliance and mechanical stability combined with the solid electrolyte.
