    摘要: A method of independently producing a negative electrode for a lithium secondary cell having thin films of lithium and a sulfide-based inorganic solid electrolyte begins with a negative electrode base material and an inorganic solid electrolyte source material being removed from closed containers in a chamber space, which is substantially inactive to lithium and insulated from air. The materials are transferred into an adjacent thin film deposition system without being exposed to the air. In the system, the source material is used to form a thin film of an inorganic solid electrolyte on the base material, to make the electrode. The electrode is transferred, without being exposed to the air, into a chamber space, which is substantially inactive to lithium, where the electrode is placed into a closed container. Thus, a negative electrode can be produced without being degraded by air.

    摘要: An electrode substrate, for a battery, as a support for an active material used in a collector for a battery, comprising a metallic porous structure possessing interconnecting pores with a porosity of not less than 90% and a number of pores per cm of not less than 10 and having an Fe/Ni two-layer structure wherein Fe constitutes the interior of a skeleton of a porous body constituting the porous structure with the surface portion of the skeleton coated with Ni. Preferably, Fe constituting the interior of the skeleton has a purity of not less than 98% by weight, and the thickness of the nickel coating layer having an Fe content of not more than 10% by weight is 0.1 to 10 .mu.m. The ratio of thickness of the Fe-diffused layer to the thickness of the Ni coating layer is regulated to not more than 0.65 by forming a metallic porous body of Fe using a porous resin as a substrate, plating the metallic porous body with Ni, heat treating the plated body.

    摘要: A porous metal body is produced by forming a coating film of one or more metal capable of forming a eutectic alloy at temperatures not higher than the melting point of Al on a foamed resin skeleton having a three-dimensional network structure according to the plating, vapor deposition, sputtering, CVD or other vapor phase process, impregnating the foamed resin having the coating film formed thereon with a paste comprising powdery Al, a binder and an organic solvent as principal components to thereby obtain a paste-coated composite and heating the composite at a temperature ranging from 550.degree. C. to 750.degree. C. in a nonoxidizing atmosphere. The resultant porous metal body has a large effective surface area and a high space utilization factor and exhibits excellent performance in uses in filters and battery plates.
