Abstract

The invention discloses a depolarization method in the foiling process of an electronic aluminum foil, wherein a depolarization process is added after each foiling process before the thermal treatment, and the depolarization process is a high-temperature water purification process in which the water purification temperature is 60-90DEG C and the treatment time is 3-5min. By adopting the depolarization method, the boosting time and the leakage current of a foil sample are effectively reduced, and the specific volume is improved.

Description
