Porous electrodes and electrolytic capacitors made therefrom

Porous anodes suitable for use in capacitors which involves forming moistened metal powder into a mass, freezing the moistened mass thereby bonding the metal powder together and sintering the mass to convert it to a porous pellet suitable for use as an anode for a capacitor. The anodes have a sinter...

Zusammenfassung:	Porous anodes suitable for use in capacitors which involves forming moistened metal powder into a mass, freezing the moistened mass thereby bonding the metal powder together and sintering the mass to convert it to a porous pellet suitable for use as an anode for a capacitor. The anodes have a sintered density below 12 g/cc and specific capacitance of at least 2,000 uFV/g.
