Abstract
A method for preparing iron electrodes is provided which includes mixing particulate iron such as iron powder, iron oxide or iron hydroxide with an organic moldable resin and, preferably, carbon black. The mixture is molded into the desired electrode configuration and the molded electrode is heated in an inert atmosphere to at least 950.degree. C. to carbonize said resin. The electrode may be thereafter activated by use of sulfur compound or the like.
Claims6
A method for the preparation of an iron electrode comprising mixing a particulate iron selected from the group consisting of an iron powder, an iron oxide and an iron hydroxide with an organic moldable resin, carbonizable at the temperatures of at least 950.degree. C., wherein the weight ratio of particulate iron to resin is from about 1:1 to about 8:1, and a small effective amount of a carbon black;
- molding said mixture into an electrode shape, and slowly heating said molded shape to at least 950.degree. C. in an inert atmosphere, to carbonize said organic resin into a porous matrix and form a mechanically strong, porous electrode;
- wherein the amount of carbon black present is effective to maintain conductivity between the matrix and the iron particles after carbonization.
