Abstract Scope |
Neutron imaging is a great tool for battery analysis as Bragg edge imaging and tomography can investigate reversible and irreversible processes happening in sodium-ion batteries (SIBs). By measuring wavelength/time-resolved transmitted neutron intensity, Bragg edge imaging allows us to obtain wide crystallographic information on the investigated material. Neutron tomography can provide essential information on morphological properties of the electrodes, such as particles’ shape, size distribution, and interface areas. With these techniques, we will investigate SIBs, in operando, to study the ionic transport and storage mechanisms, and other phenomena such as degradation upon cycling, and the dendrite growth process. Throughout the project, we will investigate Prussian blue derivatives and hard carbon, as promising electrode materials for SIBs. This multiscale and multimodal project will rely on synchrotron techniques at large-scale facilities, to complement the neutron data and benefit from the higher resolution and fast acquisition times of such instruments. |
