| Abstract: | The interaction between lithium and the ambient molten salt, 1-methyl-3-ethylimidazolium chloride/AlCl 3 system, has been studied using electrochemical impedance, cyclic voltammetry and scanning electron microscope. It is indicated that lithium reacts rapidly with the melt and two kinds of passitive film are formed on the lithium surface. Their conductivity is very low, but they can not protect the lithium from corrosion by the melt. Upon anodic polarisation stable anodic passitive films are formed on the surface of lithium. Both chemical and anodic passitive films cause that the plating-stripping process of the lithium is extremely irreversible. Thus, if the surface of the lithium is not modified by another chemical, it can be directly used into above melen salt system as a negtive electrode neither in the primary battery nor in the secondary battery. |
