摘要：
An aluminum foil is formed from an alloy of type AA1xxx, AA3xxx, and/or AA8xxx, which has a cold-solidified state and contains on its surface a rolling oil layer with a polyalkylene glycol or a compound containing a polyalkylene oxide structure. The aluminum foil has a thickness of 4 μm to 100 μm and can be easily coated with an electrode suspension for producing a battery film.
