Niobium powders and niobium electrolytic capacitors

Abstract: A flaked niobium powder is disclosed as well as electrolytic capacitors formed from the flaked niobium powders. Niobium powders having a BET surface area of at least about 0.50 m2/g are also disclosed and capacitors made therefrom, as well as niobium powders doped with an oxygen content of at least 2,000 ppm. Methods to reduce DC leakage in a niobium anode are also disclosed.

A process for making an improved tantalum powder and high capacitance low leakage electrode made therefrom

Abstract: A process for producing capacitor grade powder, electrodes, and finished capacitors therefrom having reduced electrical leakage characteristics. The powder is prepared by reacting Group V-B base materials with quantities of between 500 to 7000 ppm of nitrogen and 700 to 3000 ppm of oxygen. Electrical leakage is reduced by at least 28 % for electrodes anodized at 100 volts or greater in comparison with electrodes and finished capacitors made from undoped materials. A range of specific charge of up to 25,000 uFV/g is achieved for sintering temperatures of 1400 °C to 1800 °C.

Gas diffusion electrodes containing modified carbon products

Abstract: Gas-diffusion electrodes containing modified carbon products are described wherein the modified carbon product is a carbon product having attached at least one organic group. The modified carbon product can be used for at least one component of the electrodes such as the active layer and/or the blocking layer. Methods to extend the service life of electrodes as well as methods to reduce the amount of fluorine containing compounds are also described.
