Molten salts are non-aqueous solvents which are divided into high temperature molten salts, low temperature molten salts and room temperature molten salts. Due to their unique physical and chemical properties, they are used as the reaction and electrolytic media to electrodeposit the active metal coatings that can not be obtained in aqueous solution. In recent years, the research hot spot in the field of molten electrochemistry is that it is applicable in non-aqueous reprocessing by substituting caustic molten salts for electro-deposition and separation of actinide metal ions.
