Hybrid capacitor and method of manufacturing a capacitor

A method for forming a capacitor comprising:

• forming a working element comprising:
• forming an anode comprising a first dielectric and an anode conductive polymer layer on said first dielectric;
• forming a cathode;
• forming a separator wherein said separator comprises a separator conductive polymer layer;
• forming a layered structure comprising said anode, said cathode and said separator wherein said separator is between said anode and said cathode;
• forming a winding of said layered structure;
• impregnating said winding with a liquid electrolyte;
• and
• wherein at least one of said anode conductive polymer layer or said separator conductive polymer layer is crosslinked.
