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.

Method for the preparation of iron electrodes

A flexible substrate having a caustic resistant support and at least one membrane comprising a solid polymeric matrix containing a network of interconnected pores and interdispersed inorganic filler particles with a ratio of filler: polymer in the polymeric matrix of between about 1:1 to 5:1, is made by coating at least one side of the support with a filler:coating formulation mixture of inorganic filler particles and a caustic resistant, water insoluble polymer dissolved in an organic solvent, and removing the solvent from the mixture to provide a porous network within the polymeric matrix.
