A precise analysis of the efficiency and stability of battery active materials requires a deep investigation of the chemical and structural transformations they undergo during charge/discharge cycles. This application note presents an example of such study performed with a HORIBA’s XploRA Nano on a cathode for Li-ion batteries: thanks to the development of a dedicated electrochemical cell, nanoRaman spectra were collected during the material redox reaction and revealed a precise correlation between the sample surface structure and the electrochemical transformation kinetics.
