It is produced by the technique disclosed in Japanese Patent Publication No. 39317/1993. In this method, plating is performed by immersing the porous body, which is made conductive by coating the porous insulator with carbon particles or the like, in a plating bath while closely adhering to the rotating power feeding roll. Then, after electroplating to a predetermined thickness, heat treatment is performed to form a metal porous body made of metal (for example, nickel).

た。However, in the method of coating such carbon particles, only the porous metal body in which the carbon particles are clogged in the fine porous material and some of the pores are blocked is used. There was a problem that it could not be obtained. Moreover, when the carbon particles are coated, they are nonuniform. Therefore, when wound around a power supply roll and electroplated, a portion without carbon particles is not plated, and only a non-uniform plating film is obtained.

In addition, the method of vapor deposition of nickel has problems that the production cost is high and that it is difficult to form the vapor deposition layer quickly and accurately at the time of mass production of electrodes.

A method using hypophosphorous acid as a reducing agent has been adopted. Hereinafter, description will be made with reference to the drawings.

In this hydrophilic treatment, an alkaline, neutral or acidic aqueous solution to which a surfactant is added is used. Next, the hydrophilized porous insulator is immersed in an acid solution such as hydrochloric acid to enhance the adsorption power of the catalyst so that a plating film having high adhesion can be obtained. Then, a catalyst is attached by adsorbing a catalytic metal nucleus such as palladium (Pd) on the surface of the porous insulator. A combination of tin-palladium colloid / complex (“catalyst”) and acid is often used for this catalysis. Then, tin is removed using 5-10% sulfuric acid or hydrochloric acid to metallize Pd.

ることにより、金属皮膜を形成することが可能である。Next, electroless plating is performed on the porous insulator that has been subjected to such pretreatment. Metal ions and a reducing agent coexist in the electroless plating solution, and the reduction reaction to metal ions proceeds only around the catalyst. If electroless plating is used, it is possible to form a metal film on an insulator by adsorbing a catalyst on its surface.

うという問題もあった。However, in the pretreatment step in such a conventional electroless plating process, the adsorptive power of the porous insulator and the catalyst was insufficient. Therefore, there is a problem that the catalyst is dropped into the electroless plating solution, the reduction reaction proceeds on the surface of the dropped catalyst, and the life of the electroless plating solution is shortened. Further, there is also a problem that the plating film thickness is not sufficiently obtained in the portion where the catalyst has fallen off, which deteriorates the characteristics of the porous metal body.

ナトリウムエッチング液などが用いられる。According to the method for producing a porous metal body of the present invention, electroless plating and then electroplating are applied to a porous insulator to form a metal layer, and then the porous insulator is removed by heat treatment. The method for producing a metal porous body by using the method described above is characterized in that the surface of the porous insulator is roughened before electroless plating. The surface of the porous insulator can be roughened by, for example, corona discharge treatment. Roughening of the surface of the porous insulator can also be performed by chemical etching. The etching solution is not particularly limited as long as it etches the porous insulator, but is preferably an acid-based or alkaline-based etching solution, for example, a chromic acid-based etching solution, a sulfuric acid etching solution, or an etching solution. A manganic acid-phosphoric acid etching solution, a perchloric acid-phosphoric acid etching solution, a sodium hydroxide etching solution, or the like is used.

Therefore, as a result of making the catalyst less likely to fall off, the life of the electroless plating solution becomes longer, the productivity is improved, and the production cost can be reduced.

As a result, peeling of the coating film can be suppressed, so that the metal coating film can be uniformly formed on the porous insulator, and the characteristics of the metal porous body as the battery electrode material are improved.
