GALVANIC ELEMENT

摘要

The invention relates to a galvanic element comprising at least one lithium-intercalating electrode, the positive electrode of which has a collector substantially consisting of aluminum. The aluminum collector is coated with an adhesion promoter containing a polar modified polyvinylidene difluoride (PVDF) and an electrical conductivity improver. The electrical conductivity improver is preferably conductive soot and/or graphite or an electrically conductive polymer. The collector contains a coating of a thickness from 1 to 10 µm obtained by spraying or rolling, laminating or direct wet coating.
