Abstract

There is disclosed a process for producing an electrochemical cathode for an electrochemical cell comprised of a current collecting layer or substrate laminated between layers of a nonwoven conductive fibrous web, preferably of conductive carbon fibers, impregnated with a mixture of carbon particles and a nonfibrous polymeric substance, and optionally with a hydrophobic microporous film or layer disposed on one of the layers of the nonwoven conductive fibrous web as well as the product produced thereby.
