Patent
·
OSTI ID:7195835
An activated iron electrode material suitable for use in a battery electrode plate is described. It consists essentially of (1) iron particles consisting essentially of substantially pure iron oxides selected from the group consisting of FeO, Fe/sub 3/O/sub 4/, Fe/sub 2/O/sub 3/.H/sub 2/O and mixtures thereof and (2) the chemical reaction product of an iron particle component consisting essentially of substantially pure iron oxides selected from the group consisting of FeO, Fe/sub 2/O/sub 3/, Fe/sub 2/O/sub 3/, Fe/sub 3/O/sub 4/, Fe/sub 2/O/sub 3/.H/sub 2/O and mixtures thereof and at least one sulfur-substituted organic acid selected from the group consisting of thiolic, dithiolic, and mercapto-carboxylic acids, the mixture containing about 0.01 to 2 weight percent total sulfur. The plaque can be between 75 and 95 percent porous and the iron particle component can be selected from the group consisting of FeO, Fe/sub 2/O/sub 3/, Fe/sub 3/O/sub 4/, Fe/sub 2/O/sub 3/.H/sub 2/O and mixtures thereof.
