Identity of Passive Film Formed on Aluminum in Li-Ion Battery Electrolytes with LiPF[sub 6]
Source abstract
Abstract
The passive film that forms on aluminum in 1:1 ethylene carbonate with and 1:1 ethylene carbonate with was investigated by a combination of electrochemical quartz crystal microbalance measurements (EQCM), electrochemical impedance spectroscopy (EIS), and X-ray photoelectron spectroscopy. During anodic polarization of aluminum a film of forms on top of the air-formed oxide, creating a duplex, or two-layered film. The thickness of the increases with the applied potential. Independent measurements of film thickness by EQCM and EIS indicate that at a potential of vs , the thickness of the is approximately .
