Abstract
A method of forming a capacitor is described as is an improved capacitor formed with a one-sided capacitor foil. The method includes: providing a foil comprising a conductive core and a high surface area on each side of a first side and a second side of the core; removing at least a portion of the high surface area on the first side of the core; and forming a conductive layer on the dielectric.
Claims15
A method of forming a capacitor comprising;
- providing a foil comprising a conductive core comprising a valve metal and a high surface area layer on each side of a first side and a second side of said conductive core;
- removing at least a portion of said high surface area layer on said first side of said conductive core;
- forming a dielectric on only said high surface area layer on said second side;
- forming a conductive cathode layer on said dielectric with an isolating material circumscribing an area of said conductive cathode layer wherein said forming of said conductive cathode is after said removing of said at least a portion of said high surface area layer;
- and
- forming an anode termination on said first side of said conductive core.
