There is a growing interest in nanostructured electrode materials due to their desirable kinetic properties. But their nanoscopic nature renders characterisation via diffraction technique challenging.
Structural defects and disorder (e.g. displacement, stacking faults, occupational disorder, etc) are frequently observed in electrode materials. These structural features are closely related to materials’ reactivities.
Batteries are heterogeneous systems where redox reactions take place upon cycling. Thus understanding materials’ intricate phase behaviour is a prerequisite for a mechanistic study of their performances.
