Abstract

In a method for forming an electrolyte film on an electrode surface, the liquid electrolyte is sprayed into a cavity to form an electrolyte mist; the electrolyte mist exits the cavity through an opening and then flows across the electrode surface, which is directed downward at an angle behind the opening, whereby an electrolyte film is formed on the electrode surface and wherein the thickness of the electrolyte film is set by means of the angle of inclination of the electrode surface. A corresponding device includes an electrolyte tank communicating with a mist chamber for accommodating sprayed electrolyte by means of a spraying apparatus, wherein the mist chamber comprises a mist outlet. Furthermore, a retainer for fixing the electrode surface at a specifiable angle of inclination is provided, so that electrolyte mist, which can exit through the mist outlet, flows across the electrode surface to form an electrolyte film.
