Abstract
A method for manufacturing an electrolytic capacitor with improved deformation qualities includes impregnating an electrolytic capacitor with a first electrolyte, aging the electrolytic capacitor after impregnating and reimpregnating the electrolytic capacitor with a second electrolyte. The water content of the second electrolyte is lower than the water content of the first electrolyte. The second electrolyte may also have a lower viscosity and a higher conductivity than the first electrolyte.
