In Situ and Operando Neutron Powder Diffraction of Na x NiO 2 : A Case Study for Sodium-Ion Batteries
Neutron powder diffraction (NPD) is a non-destructive technique uniquely suited to investigating industrially relevant sodium-ion cathode materials. Unlike X-ray diffraction, it offers excellent contrast between neighbouring transition metal ions and is sensitive to lighter elements such as O/Na, which are key to r...
