Structural and electronic studies of metal hexacyanoferrates-based cathodes for Li and Na rechargeable batteries

Achievements: XANES and EXAFS spectra on the newly prepared Co and Cu hexacyanoferrates cathodes for lithium batteries have been recorded at the XAFS beamline. The beam time session was extremely successful because not only the spectra were acquired at the all available metal K-edges (Co/Fe and Cu/Fe), but also the experiments have been done using an optimized operando cell, allowing to check main structural and electronic changes during the charge and discharge processes of the battery
