PRODUCTING METHOD FOR ELECTRODE FOIL FOR HIGH VOLTAGE STACKED TYPE ALUMINIUM CAPACITOR

摘要

The present invention relates to a method for manufacturing an electrode foil of a stacked aluminum capacitor for a high voltage and, more specifically, to a method for manufacturing an electrode foil of a stacked aluminum capacitor for a high voltage gradually performing a hydration treatment process, a first conversion treatment process, and a heat treatment process on an etched aluminum electrode foil and including a phosphating treatment process in which the aluminum electrode foil passing through the heat treatment process is sunken in an aqueous solution of phosphate or phosphoric acid.
