ELECTRODE MATERIAL FOR ALUMINUM ELECTROLYTIC CAPACITOR, AND METHOD FOR PRODUCING SAME |
摘要 |
An electrode material for an aluminum electrolytic capacitor, comprising, as constituent elements, sintered body of a powder of at least one member selected from the group consisting of aluminum and aluminum alloys, and an aluminum foil substrate supporting the sintered body thereon, wherein (1) the powder has an average particle size D50 of 0.5 to 100 μm, (2) the sintered body is formed on one surface or both surfaces of the aluminum foil substrate and has a total thickness of 10 to 1,000 μm, (3) the porosity of the sintered body is 35 to 49% by volume, and (4) the sintered body is obtained by applying a rolling process to a film made from a composition comprising a powder of at least one member selected from the group consisting of aluminum and aluminum alloys, and subsequently sintering the film. |
