NanoBat aims to develop a novel nanotechnology toolbox for quality testing of Li-ion and beyond Lithium batteries which will be faster and more accurate than existing methods. Like this, NanoBat will help to reduce the environmental footprint of battery production, support the evolving clean energy transition and increase the competitiveness of the e-mobility battery sector in Europe.
Sustainable storage of electrical energy is among this century’s main challenges, and – as stated by the European Commission – battery production is one of the future key industries with an estimated market potential of EUR 250 billion by 2025. About one third of the production costs is related to the formation phase of the electrode SEI (solid electrolyte interphase) – an electrically insulated layer preventing ongoing electrolyte decomposition. In order to create a competitive manufacturing value chain for sustainable battery cells in Europe, reliable methods for measuring the quality and performance of batteries are of pivotal importance.
The NanoBat Approach
With the aim of surpassing currently available non-destructive quality testing techniques, NanoBat has set out to develop an RF-nanotechnology toolbox to test Li-ion and beyond Lithium batteries. With a particular focus on the nanoscale structure of the SEI layer, this toolbox will contain novel high-frequency GHz methods to test and quantify the electrical processes at the SEI which are responsible for battery performance and safety, but diicult to characterise and optimise.
