ANISSA: Advanced Neutron Imaging for Solid-State batteries in Action

The development of high-energy density solid-state batteries is critical for the achievement of carbon neutrality goals and the advancement of clean energy. Still, the fundamental understanding of lithium transport mechanisms and degradation processes remains limited. Current characterisation methods face significant challenges in studying these complex systems, particularly due to the difficulty of detecting lithium dynamics in three-dimensional battery architectures in operando conditions. Here we present the ANISSA (Advanced Neutron Imaging for Solid-State batteries in Action) project, an integrated experimental framework combining high-resolution neutron and X-ray imaging techniques to research coupled electro-chemo-mechanical processes in lithium-based energy storage systems. • The new project ANISSA will bring new insights into electro-chemo-mechanical processes within solid-state batteries. • Multimodal high-resolution 5D imaging is the best non-destructive frontier method to study solid-state batteries.
