A self-supporting electrode structure consisting of active material particles is made by: (1) mixing 100 parts of metallic iron particles, with between about 0.5 part to about 5.0 parts of a water soluble metal sulfate selected from MgSO4, CdSO4, MnSO4, ZnSO4, BaSO4, Cr2(SO4)3, CuSO4, CaSO4, Li2SO4, their hydrates and mixtures, as an electrochemical activator, and an amount of water effective to form a thin coating of metal sulfate on the metallic iron particles, (2) sizing the mixture to between about 10 microns to about 275 microns average particle size, (3) pressing the coated iron particles, and (4) reducing and sintering the coated iron particles at between about 700 DEG C to about 1,000 DEG C, in a reducing atmosphere; to provide an interconnected self-supporting metallic electrode structure consisting solely of fully charged iron active material particles coated with the metal of the additive, said electrode being capable of immediate discharge. |
