Abstract
This disclosure is directed to strengthening carbon black-particulate "Teflon" (PTFE) mixes destined to be formed into active layers in air cathodes, which comprises forming the carbon black-particulate Teflon mix; fibrillating said mix along with a substantial quantity of soluble pore-forming agent; adding polytetrafluoroethylene (PTFE) fibers while chopping said fibrillated mix; and thereafter rolling said chopped fibrillated mix containing said PTFE fibers into sheet form.
