XAFS of the manganese K-edge in LiMn2O4 has allowed the chemical and structural effects of lithium extraction and reinsertion to be characterised and attributed to oxidation-reduction processes. Structural information in the experimental data at low k, as well as that relating to scatterers beyond the first two coordination shells, can be accurately analysed using ab initio curved-wave multiple scattering simulations.
