METAL POROUS BODY AND METHOD FOR MANUFACTURING THE SAME, AND BATTERY USING THE METAL POROUS BODY

摘要

PROBLEM TO BE SOLVED: To provide a metal porous body capable of being used as a battery electrode, in particular, as a negative electrode of a molten salt battery using sodium.

SOLUTION: A metal porous body includes: a hollow metal skeleton comprising a metal layer mainly composed of nickel or copper; and an aluminum-covered layer covering at least an outside surface of the metal skeleton. Further, a tin-covered layer covering the aluminum-covered layer is provided to be used as a battery electrode. Preferably, the metal porous body includes continuous pores formed by a skeleton constituting a three-dimensional network structure, and has a porosity of 90% or more.
