New procedures have been developed for the preparation of electrodes possessing exceptional mechanical stability and, for different purposes, electrodes from slurries of carbon without added dispersants. Stable electrodes can be fabricated by including high polymers in the dispersion as binding materials. The incorporation of 3% ethylene propylene terpolymer in a toluene slurry of carbon imparts the desired stability to the finished electrodes without affecting the capacity. Generally, electrodes prepared from slurries containing only water and carbon displayed relatively poor mechanical stability, with the exception of mixtures of various carbons with graphite. Although water slurries of carbons and carbon mixtures are unstable, satisfactory electrodes can be prepared by using proper precautions. These electrodes allow determination of the demineralization behavior of carbons without the complicating presence of binders or dispersants. (Author)
