摘要： Disclosed is an electrolytic direct energy converter (EDEC) having a cell that produces electrical energy based on the dynamics of electrically mobile ions within a gel, fluid or solid state electrolyte that is in electrical contact with a pair of electrodes of the cell. The pair of electrodes are physically separated from one another within an electrolyte such that an electric field is generated therebetween. The motion of the ions in the electrolyte causes more of the positive ions to move to one of the pair of electrodes and more of the negative ions to move to the other one of the pair of electrodes whereby to produce a potential voltage. An external electrical load impedance is electrically connected between the pair of electrodes such that the potential voltage is produced by the cell across the load impedance and a current flows through the load impedance.

摘要： Fabricating a capacitor includes performing an oxide formation operation on a sheet of material. The oxide formation operation forms an anode metal oxide on an anode metal. A thermal compression is performed on the sheet of material after the oxide formation operation is performed. The thermal compression applies thermal energy to the sheet of material while applying pressure to the sheet of material. After the thermal compression, the capacitor is assembled such that at least one electrode in the capacitor includes at least a portion of the sheet of material.

摘要： A method of manufacturing high capacitance anode and cathode films of capacitors is revealed. Perform sputter deposition on a cathode aluminum foil in a vacuum chamber to form a cathode metal layer which is a titanium layer on a surface of the cathode aluminum foil. Then titanium continuously reacts with nitrogen to form cathode columnar crystal deposition on a surface of the cathode metal layer and get a cathode film. Perform sputter deposition on an anode aluminum foil in a vacuum chamber to form an anode metal layer which is a titanium layer on a surface of the anode aluminum foil. Then titanium continuously reacts with oxygen and nitrogen to form anode columnar crystal deposition on a surface of the anode metal layer and get an anode film. Next use the cathode and anode films with high capacitance to form cathode and anode electrodes of the capacitor.

摘要： An electrode holder and a method for producing an electrode for an aluminum electrolytic capacitor are provided that enable prevention of exfoliation of a porous layer during chemical formation even when the porous layer is formed on an aluminum electrode so as to have a thickness of 200 micrometers or greater. When an aluminum electrode 10 having at least one surface 11 on which a porous layer 17 having a thickness of 200 micrometers or greater is formed is subjected to chemical formation in a chemical formation solution, the aluminum electrode 10 is held by an electrode holder 50. The electrode holder 50 includes: an insulating first support plate 51 configured to overlap the one surface 11 of the aluminum electrode 10; an insulating second support plate 52 configured to overlap the other surface 12 of the aluminum electrode 10; and a connecting part 53 configured to connect the first support plate 51 and the second support plate 52 to each other. A portion of the first support plate 51 that overlaps the porous layer 17 while being in contact therewith is formed with a porous member 510.

摘要： An electrode for an aluminum electrolytic capacitor and a method for producing the same are provided that enable improvement of water resistance of a chemical formation film having a withstand voltage of 400 V or higher.
The electrode for an aluminum electrolytic capacitor is produced by performing a hydration step of bringing the aluminum electrode into contact with a hydration treatment liquid having a temperature of 78° C. to 92° C. to form a hydrated film on the aluminum electrode and a chemical formation step of performing chemical formation at a chemical formation voltage of 400 V or higher in a chemical formation solution having a temperature of 58° C. to 78° C. to form the chemical formation film on the aluminum electrode. In this method, the amount of the hydrated film is made appropriate. In this electrode for an aluminum electrolytic capacitor, the number of voids that are exposed on a cut surface when the chemical formation film is cut is 150 voids/μm2 or smaller, and thus the water resistance thereof is high.
