Galvanic element

Galvanic element (A) comprises at least a lithium-intercalated electrode, whose positive electrode possesses an aluminum collector that exhibits a covering layer consisting a benzotriazole derivative. Independent claims are also included for: (1) a positive-electrode-collector compound, for (A) (preferably a galvanic element in pile technology), comprising an aluminum collector that exhibits a covering layer consisting a benzotriazole derivative; and (2) a method for preparing the positive-electrode-collector comprising coating an aluminum collector with the covering layer consisting a benzotriazole derivative and applying (optionally after temporary storage) the obtained covering layer on the positive-electrode-collector.
