摘要：

The electrochemical behaviour of a Li electrode in solutions of LiAlCl4 in thionyl chloride, LiBF4 in gamma-butyrolactone and LiClO4, in the mixed solvent propylene carbonate (PC); dimethoxyethane (DME) in the process of cell storage has been investigated by the methods of electrode impedance spectroscopy and pulse voltammetry. Analogous studies have been carried out in PC + DME solution with the Li electrode coated with a specially formed protecting film of Li2CO3. The results have been compared with those obtained earlier for other lithium electrochemical systems. The general regularities of the Li electrode electrochemical kinetics attributed to the process of Li+ ion transport through a passivating film coating a lithium surface have been discussed.
