Abstract
The intercalation process of Li+ in spinel LiMn2O4 thin films in 1 mol /L LiClO4 + PC solution has been investigated using EQCM method, The r esults indicate that a passive solvent film is formed on the lithium-m anganese-oxides;electrode surface in PC solvent. The Li+ intercalation is a main process in the potential range between 2.5 similar to 3.25 V. However, the decomposition of the solvent film and de-intercalation of Li+ occur simultaneously when the electrode potentials are control led between 3.7 similar to 4.1 V.
