COPPER FOIL FOR LITHIUM ION BATTERY CURRENT COLLECTOR

摘要

Disclosed is a copper foil for a lithium ion battery current collector, in which the adhesion to a negative electrode active material and anti-corrosive properties are improved in a good balance. In the copper foil for a lithium ion battery current collector, a mixed layer comprising an azole compound and a silane coupling agent is formed on at least a part of the surface of a copper foil.
