Abstract: The construction and characteristics of sample cell used for electrochemical in situ Raman spectra research on molten salts in the previous literatures and the development in that research field were reviewed.The sample cells in the previous researches were mainly used for the right（θ=90°）scattering mode,and the measurements were usually carried out under inert atmosphere.The constant current or constant potential method was mainly used,and the research involves the cathodic behavior of electrolysis of metal Al,Hg,Cd,and Ta in molten chloride,reduction process of oxygen in molten（Li-K）CO3and Li2CO3,electrochemical process of I2 in molten AlCl3-NaCl of the high energy molten salt battery using metal aluminum as the anode,behavior of element sulfur in molten AlCl3-NaCl during the discharge process of sodium-sulfur battery,the electrochemical corrosion of oxygen ion conductor of Y2O3-stabilized ZrO2 in molten Na2SO4,and the change on structure of melts in the interface between molten KNO3 and NaNO3and platinum electrode.At last,the development directions of the electrochemical in situ Raman spectroscopy in molten salts are pointed out.
