Consequences of different choices for the cutoff radius, R_cutoff, on the values of the bond valence parameters, R₀ and b, for Li−O bonds. (a) Refined value of R₀, (b) refined value of b, (c) average difference between the atomic valence and the bond valence sum calculated with the bond valence parameters refined at this cutoff, (d) bond valence at the cutoff calculated with the corresponding bond valence parameters.
