The electrochemical deposition and stripping of lithium have been examined using three-electrode cells with a polyethylene oxide-lithium trifluoromethanesulphonate polymer electrolyte. The results show that the process is reversible, but that the kinetics are influenced by the nature of the electrod

โฆ Synopsis
Active metal nonaqueous
systems can be divided into three groups: (a) solid electrolyte interphase (SEI)-free, aqueous-like, active-metal nonaqueous systems, such as aluminium plating baths; (b) metal solvent blue solutions, or solvated electron systems; (c) SE1 battery systems. It is concluded that the only type of system that can be applied in primary and secondary lithium batteries is the SE1 electrode system. The following are presented and discussed: The deposition-dissolution mechanism and the kinetics of SE1 electrodes, the effect of several parameters on the resistivity of the SEI, the growth rate of the SEI, the morphology of the overall passivating layer and the voltage delay problem.
