In situ FT Raman spectroelectrochemistry with the near infrared laser beam has been conducted on the binder included electrodes of the over loaded LiCoO2 and LiMn2O4 based cathode active materials with the PVdF binder in the LiPF6 electrolyte systems.In our previous In Situ Raman works using visible laser beams, we have generally used the thin film electrode materials with LiClO4 electrolyte solution systems.
