ABSTRACT:
Iron disulfide electrodes are prepared by: slurrying the FeS.sub.2 in molten sulfur; spreading the slurry into FeS.sub.2 --S sheets; solidifying the FeS.sub.2 --S sheets; sandwiching the FeS.sub.2 --S sheets between porous current-conductor sheets; and heating the thusly formed sandwich to volatize away the sulfur. Flexible FeS.sub.2 --S sheets are obtained by heating the slurry to about 300.degree. C and then rapidly quenching them in H.sub.2 O.
