Overview of 3D ED / EDT for determining crystal structures of lithium battery cathode materials
What is it about?
The paper is a review of case studies and tips and tricks to solve and refine the crystal structures of specifically lithium battery cathode materials using quantitative electron diffraction (3DED, EDT, PED, micro-ED,...).
Why is it important?
Whereas the active materials can only be studied in powder diffraction form using X-rays and neutrons because the active particles are too small, we can obtain single crystal data on each particle separately if we use electron diffraction. Single crystal data gives a much clearer view of the reciprocal space and thus a more conclusive solution of the structure. In many cases there is certain information that can only be obtained through the electron diffraction methods, especially when the powder methods are clouded by the presence of multiple phases.
