摘要:
A capacitor has a positive electrode 10, a negative electrode 20, and a solid electrolyte layer arranged between the electrode layers 10 and 20. At least one 10 (20) of the electrode layers of this capacitor 100 has an Al porous body 11, and an electrode body 12 (13) held in this Al porous body 11 to polarize the electrolyte. The oxygen content in the surface of the Al porous body 11 is 3.1% by mass or less. The matter that the oxygen content in the surface of the Al porous body 11 is 3.1% by mass or less is equal to the matter that a high-resistance oxide film is hardly formed on the surface of the Al porous body 11. Thus, this Al porous body 11 makes it possible to make the current collector area of the electrode layer 10 (20) large so that the capacitor 100 can be improved in capacity.
摘要:
There is provided a metal laminated structure (100) comprising a first metal layer (1), a second metal layer (2) and a third metal layer (3), the first metal layer (1) being disposed on one surface of the second metal layer (2), the third metal layer (3) being disposed on the other surface of the second metal layer (2), the first metal layer (1) including at least one of tungsten and molybdenum, the second metal layer (2) including copper, the third metal layer (3) including at least one of tungsten and molybdenum, and a method for producing the metal laminated structure (100).
