Abstract
1293333 Electrolytic capacitors YUASA BATTERY CO Ltd 23 Jan 1970 [12 Feb 1969] 3423/70 Heading H1M In the manufacture of an electrolytic capacitor a porous spacer 1 is formed by applying to the anodized anode foil or cathode foil 4 either (A) a solution of a synthetic resin containing a liquid which is a poor solvent for the resin but is miscible with the solvent, and drying or (B) a solution of a synthetic resin, then contacting the coated foil with the poor solvent liquid or its vapour, then drying. Preferably the solvent is more volatile than the poor solvent. Various combinations of resin, solvent and poor solvent are specified. The method yields pores having the shape shown, i.e. of greater cross-section at the base. The foil to be coated may be pre-treated with the poor solvent to prevent the resin from filling etched bits. The resin coating may include titanium dioxide, silica or powdered resin.
