Formation process of passivating film and film formation mechanism of aluminum current collector as lithium secondary batteries in typical orgphenomenarolytes for lithium secondary batteries have been investigated using galva-nostatic and potentiostatic condition with some surface analysis methods such as XRD and XPS. These data were also compared with the phenomena in aqueous solution system. Aluminum current collector formed compact passivating film of barrier type, and this film consisted of AlF3 related compounds as main components. The formation of passivating film followed the high field model, which was similar to that for the aluminum anodic oxide formation in neutral aqueous solution.
