摘要： A method of non-thickness-limited anodizing for valve metals and alloys which are resistant to the non-thickness-limited growth of anodic oxide, such as niobium and high niobium content alloys. Non-thickness-limited anodic oxide film growth is produced on such valve metals by employing a first glycerine-based electrolyte containing about 1 to about 3 wt % water for the initial production of anodic oxide. After the substrate is anodized using the first electrolyte, it is immersed in a second glycerine-based electrolyte having less than about 0.1 wt % water. The second electrolyte may be produced by allowing water to evaporate from the first electrolyte solution until the solution contains less than about 0.1 wt. % water.

摘要： Methods for anodizing sintered valve metal anodes for use in wet electrolytic capacitors implemented in implantable medical devices (IMDs). The methods generally include immersing a pressed valve metal anode in an anodizing electrolyte and developing an anode-electrolyte system. Subsequently, subjecting the anode-electrolyte system to a potential that is ramped up to a target voltage in a pulsed fashion and delivering voltage potential pulses to the anode. The pulses are preferably decreased in pulse width as the potential increases. The pulse width of the applied pulses is preferably defined by means of a duty, such that the applied pulse duty cycle is substantially 100% initially and declines over the formation time as the formation voltage increases to the target potential to substantially 1.0% or less. The pulses are preferably applied for a hold time following achievement of the target formation potential, as the pulse current declines toward zero current flow.

摘要： A non-aqueous electrolyte comprises an organic solvent and a solute, and also has an electrolytic conductivity that is greater than or equal to 1 mS/cm but less than or equal to 100 mS/cm. This solute preferably includes at least one of a carboxylate and a salt of inorganic oxoacid. In addition, the non-aqueous electrolyte preferably comprises water in a proportion of 1 to 10 wt %. In an MIM nonlinear element (20), an insulated film (24) is formed by anodic oxidation using the above non-aqueous electrolyte. In addition, the insulated film comprises at least one of carbon atoms and atoms of families 3 to 7 that were originally the central atoms of the salt of inorganic oxoacid, and has a relative permittivity of 10 to 25. With this MIM nonlinear element, the capacitance is sufficiently small, the steepness of the voltage-current characteristic is sufficiently large, and also the resistance is sufficiently uniform over a wide area.
