Description
Lithium-ion batteries have revolutionized our lives and they, in conjunction with alternative battery chemistries such as sodium-ion batteries, are going to shape our lives in the near-future. Electrodes account for a significant proportion of battery function, where atomic-scale perturbations or changes in the crystal structure during an electrochemical process permit the reversible insertion/extraction of charge carriers. Therefore, determining the interplay between crystallography and electrochemistry is essential to understand and rationalize in order to deliver better materials and batteries.
A large fraction of our work investigates the structure-electrochemistry relationship in-situ or operando using both neutron and synchrotron X-ray diffraction. In other words, exploring electrode structure evolution while a battery is operating. This presentation will showcase operando and in situ neutron powder diffraction studies on commercial lithium-ion batteries and operando and in situ X-ray powder diffraction studies on ambient temperature rechargeable sodium-ion batteries. With the information from these experiments one can directly relate electrochemical properties such as capacity, battery lifetime, applied rates and differences in charge/discharge to the content and distribution of sodium in the electrode crystal structures or the lattice parameter evolution.
