Abstract
A method for production of high storage capacity elements for electrolytic capacitors, comprising the steps of producing unetched metal filaments, oxidizing the filaments at a forming voltage so as to coat them with an oxide layer. To obtain high specific storage capacity, the radius of the metal filament (r.sub.1) is determined in accordance with the maximum operating voltage (U) and the maximum field strength (E.sub.m) of the dielectric so that the radius r.sub.1 lies within the range of ##EQU1## In an arrangement of the electrolytic capacitor with capacity elements made by this method, to reduce the unproductive volume, a plurality of capacitor elements are electrically connected in parallel while the oxide layers on adjacent capacitor elements are close to one another.
