Motivation
The commercialisation of sodium-ion batteries (NIBs) is still in its infancy, but has recently picked up speed. In order to increase the cost efficiency and sustainability of NIBs, it is important to take an in-depth look at key production processes. This project therefore focuses on the development of environmentally friendly and economically viable cathode and anode production processes for NIBs. The active materials selected for this research project should consist of sufficiently available, easily procurable, easily recyclable and preferably non-toxic materials. In addition, the project will develop and evaluate water-based and high viscosity processing techniques for the production of NIB electrodes. By applying state-of-the-art process technologies from active process research in lithium-ion battery production (including the ProZell competence cluster) and by gaining a deep understanding of the underlying process-structure-property functions, the project aims to contribute to a significant further development of NIB production. In addition, all relevant process routes, process steps and materials used will be evaluated from an environmental perspective as part of a life cycle assessment.
Project Goals
The aim of this project is to increase the efficiency and sustainability of NIB production using innovative process strategies. Building on the experience gained in the production of LIBs, the transfer to innovative and environmentally friendly process routes, such as water-based or high-viscosity production of the electrodes, will be established at an early stage. The ultimate goal is to demonstrate sustainably and efficiently produced multi-layer full cells with a state of health (SoH) of at least 90% after 1,000 cycles.
