The Neutron Battery Hub (NBHub) is a 5-year collaborative scientific programme hosted at ILL. The NBHub brings together battery scientists, neutron experts, data scientists, and theoreticians to develop a centre of excellence in neutron-based characterisation of battery materials and devices. I

t addresses key challenges in Li-ion, Na-ion, and all-solid-state technologies through multi-technique neutron experiments to explore the structural, chemical and morphological changes happening in a battery during its lifetime. Moreover, it aims at establishing structure-transport-function relationships based on understanding fundamental reaction and degradation processes in both ex situ and in operando conditions.

Core neutron techniques are diffraction, imaging, small-angle scattering and inelastic/quasielastic scattering.

The NBHub is anchored in ILL's state-of-the-art instrument suite, and builds on a network of leading academic and industrial partners across France and Europe (CEA, CNRS, ESRF European Battery Hub, Battery 2030+ and others).
