A capacitor with an anode, a dielectric on the anode and a cathode on the dielectric. A blocking layer is on the cathode. A metal filled layer is on said blocking layer and a plated layer is on the metal filled layer.

Solid electrolytic capacitors with improved reliability

A method for forming a capacitor including forming an anode from a valve metal; forming an oxide on the anode to form an anodized anode; dipping the anodized anode into a slurry of conductive polymer; drying the intrinsically conductive polymer; and providing external terminations in electrical contact with the anode and the conductive polymer.

High voltage solid electrolytic capacitors using conductive polymer slurries

A method for maintaining quality of monomer during a coating process for intrinsically conductive polymer which suppresses unwanted by-products. A neutralization process using a base or anion exchange resin is used batch-wise or continuous.

Process for manufacturing low ESR conductive polymer based solid electrolytic capacitors

Porous sintered anode bodies for capacitors formed from valve metals are treated by electrolysis to form a dielectric layer and coated with cathode layers. When standard parallelpiped shapes are used, cathode coverage at the edges and corners is non-uniform and failures occur at those locations. Rectangular prisms, obround prisms and cylindrical prisms are formed with transition surfaces at edges and corners, such as chamfers and curves, to enhance cathode layer uniformity. The transition surface greatly enhances the application of polymer slurries.

Anodes with corner and edge modified designs

An improved capacitor with an anode with an anode wire and an oxide layer on the surface of the anode. A cathode layer is exterior to the oxide layer. A carbon conductive layer is exterior to the cathode layer wherein the cathode layer comprises 5-75 wt % resin and 25-95 wt % conductor. The conductor has carbon nanotubes. An anode lead is in electrical contact with the anode wire and a cathode lead is in electrical contact with the carbon conductive layer.

Electrode compositions containing carbon nanotubes for solid electrolyte capacitors

An anode with an anode body with a first side and a second side opposite to said first side, multiple anode wires and a conductive polymer cathode.

Fluted anode with minimal density gradients and capacitor comprising same

An anode with narrow flutes (&#x3c;0.3 mm) allows for the improved penetration of cathode solutions into the anode body and reduces the redistribution which occurs as the solutions are converted to the solid cathode material.

Fluted anode with improved capacitance and capacitor comprising same

An anode with an anode body with a first side and a second side opposite to said first side. First flutes are on the first side and second flutes on the second side. The first flutes and said second flutes are offset or have different depths.
