How is the temperature factor (B) value determined during Rietveld refinement to quantify Ni/Li site mixing in NCM cathodes?

The temperature factor (B) parameter in the context of Rietveld refinement is typically defined as the isotropic atomic displacement parameter, representing the extent of atomic vibrations or...

How can the extent of Ni incorporation into Li sites be quantitatively assessed via the Ni–Li mixing ratio using Rietveld refinement of XRD data?

I'm working with NCM (Nickel Cobalt Manganese) cathodes, where nickel (Ni) partially substitutes for lithium (Li) in the crystal structure. I'm looking for methods to quantitatively determine the...
