摘要： A hybrid polymer aluminum electrolytic capacitor and a method for manufacturing a capacitor are disclosed. In an embodiment a method for manufacturing a capacitor includes winding an anode foil, separators and a cathode foil around an axis to form a winding element, flooding the winding element with a polymer dispersion, wherein the polymer dispersion contains electrically conductive solid polymer particles or a polymer powder and a solvent and applying pulses of overpressure to the flooded winding element.
