摘要:
A method of producing an electrode includes the steps of filling an active material in an electrode substrate made of woven or non-woven fabric having its fiber surface coated with metal, and pressing the electrode substrate to obtain an electrode, wherein the pressing is performed using the electrode substrate having a thickness of less than 2.0 t when the thickness of the electrode after the pressing is t. This ensues that the electrode substrate has a thickness allowing the active material of a sufficient amount to be filled therein, and a battery electrode in which the filled active material is unlikely to peel off from the electrode substrate can be produced. Accordingly, a battery electrode having a desired thickness and desired capacity and that can suppress degradation in battery performance due to repeated charge and discharge, and its producing method are provided.

An electrode plate for a battery is constructed from a porous metal body having at least one low-porosity part selectively arranged therein. A porous resin core is coated with a paste having a metal component, passed through rolls provided with at least one recess to thereby form at least one low-porosity part and sintered. The resultant electrode plate for battery is not only ensured with respect to strength and capable of improving battery performance but also advantageous in that it is available at lowered cost and free from apprehension of supply of raw materials.
摘要:
A process for manufacturing a plastic package type semiconductor device composed of a rolled metal substrate made of copper or copper alloy and an insulating film formed on the surface of the substrate. The film may be a single-layer film made of silicon oxynitride or a composite film formed by laminating a silicon oxide layer and a silicon oxynitride layer (or a silicon nitride layer). A semiconductor element is mounted on the film or on the exposed surface of the substrate. Other passive elements are provided on the film. After connecting these elements with bonding wires, the entire device is sealed in a resin molding. This device is thus free of cracks due to difference in thermal expansion between the film and the substrate, or peeling due to moisture absorption.

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.
